Trypanosoma brucei causes African trypanosomiasis and contains three full-length oligosaccharyltransferase (OST) genes; two of which, TbSTT3A and TbSTT3B, are expressed in the bloodstream form of the parasite. These OSTs have different peptide acceptor and lipid-linked oligosaccharide donor specificities, and trypanosomes do not follow many of the canonical rules developed for other eukaryotic N-glycosylation pathways, raising questions as to the basic architecture an ...[more]

Probing endogenous peptide acceptor substrate specificities of TbSTT3A and TbSTT3B

Project description:We performed glycoproteomics on endogenous parasite glycoproteins using sequential endoglycosidase-H and peptide-N-glycosidase-F digestions, the latter in the presence of H2[18O]. This allowed us to assess the relative occupancies of native N-glycosylation sites by endoglycosidase-H resistant N-glycans originating from Man5GlcNAc2-PP-dolichol transferred by TbSTT3A, and endoglycosidase-H sensitive N-glycans originating from Man9GlcNAc2-PP-dolichol transferred by TbSTT3B.

N-glycosylation site occupancy in human prostaglandin H synthases expressed in Pichia pastoris

Project description:Prostaglandin H synthases (PGHSs) are N-glycosylated membrane proteins that catalyse the committed step in prostaglandin synthesis. Unlike PGHS-2, the production of recombinant PGHS-1 in non-mammalian expression systems is complicated. The majority of the heterologous enzyme is inactive due to misfolding. N-glycosylation is proposed to be obligatory for the correct folding of mammalian PGHSs. In this study, human PGHS-1 and -2 (hPGHS-1 and -2) were expressed in the yeast Pichia pastoris, and the N-glycosylation patterns of the purified recombinant proteins were characterised using nano-LC/MS/MS. Recombinant hPGHS-2 was catalytically active, whereas hPGHS-1 was inactive. Unexpectedly, the accumulation of non-glycosylated hPGHS-1 was not observed in the crude lysate of the yeast cells. In addition, the purified hPGHS isoforms exhibited similar N-glycosylation site occupancy. The results indicate that there are more complex grounds for the inactivity of the recombinant hPGHS-1 produced in yeast.

Soybean seed germination LC-MS/MS

Project description:This study aims at addressing soybean seeds (variety Absolute RR) germination, at 48h, during optimal and salt stressed condition when treated with bacterial signal compounds lipo-chitooligosaccharide (LCO) and thuricin 17 (Th17). Soybean growth is negatively affected when exposed to 40 mM NaCl and exposure to 80 mM NaCl is often lethal. When treated with the bacterial signal compounds lipo-chitooligosaccharide (LCO) and thuricin 17 (Th17), soybean seeds (variety Absolute RR) responded positively at salt stress of up to 150 mM NaCl. Shotgun proteomics of unstressed and 100 mM NaCl stressed seeds (48 h) in combination with the LCO and Th17 revealed many known, predicted, hypothetical and unknown proteins. In all, carbon, nitrogen and energy metabolic pathways were affected under both unstressed and salt stressed conditions when treated with signals. PEP carboxylase, Rubisco oxygenase large subunit, pyruvate kinase, and isocitrate lyase were some of the noteworthy proteins enhanced by the signals, along with antioxidant glutathione-S-transferase and other stress related proteins. These findings suggest that the germinating seeds alter their proteome based on bacterial signals and on stress, the specificity of this response plays a crucial role in organ maturation and transition from one stage to another in the plants life cycle; understanding this response is of fundamental importance in agriculture and, as a result, global food security.

Arabidopsis rosettes proteome in response to LCO and Th17 under salt stress- LC-MS/MS

Project description:Lipo-chitooligosaccharide (LCO) and thuricin 17 (Th17) are two bacterial compounds that have been shown to positively influence plant growth of both legumes and non-legumes. Arabidopsis thaliana responded positively to treatment with the bacterial signal compounds LCO and Th17 in the presence of salt stress (up to 250 mM NaCl). Shotgun proteomics of unstressed and 250 mM NaCl stressed A. thaliana rosettes (7 days post stress) in combination with the LCO and Th17 revealed many known, putative, hypothetical and unknown proteins. Overall, carbon and energy metabolic pathways were affected under both unstressed and salt stressed conditions when treated with these signals. PEP carboxylase, Rubisco-oxygenase large subunit, pyruvate kinase, and proteins of photosystem I and II were some of the noteworthy proteins enhanced by the signals, along with other stress related proteins. These findings suggest that the proteome of A. thaliana rosettes is altered by the bacterial signals tested, and more so under salt stress, thereby imparting a positive effect on plant growth under high salt stress. The roles of the identified proteins are discussed here in relation to salt stress adaptation, which, when translated to field grown crops can be a crucial component and of significant importance in agriculture and global food production.

PRMT-7/PRMT7 activates HLH-30/TFEB to guard plasma membrane integrity compromised by pore-forming toxins

Project description:This research reveals that protein arginine methyltransferase-7 (PRMT-7) is indispensable to the nuclear transactivation of HLH-30. We demonstrated that PRMT-7 participates in the methylation of HLH-30 on its Rag complex binding domain to facilitate its nuclear localization. Moreover, we showed that PRMT7 is evolutionarily conserved to regulate TFEB cellular localization and repair plasma damage caused by PFTs in human intestinal cells.

Structural and functional studies of CC chemokine receptor 5 phosphorylation and its interactions with arrestin2

Project description:The two non-visual arrestin isoforms, arrestin2 and arrestin3, recognize and bind hundreds of G protein-coupled receptors (GPCRs) with different phosphorylation patterns leading to distinct functional outcomes. Whereas the impact of phosphorylation of the vasopressin 2 receptor and rhodopsin on arrestin interactions has been well studied, much less known for other GPCRs. Here we have characterized the interaction between the phosphorylated CC chemokine receptor 5 (CCR5) and arrestin2. Mass spectrometry and biochemical revealed several new CCR5 phosphorylation sites, which proved essential for the formation of stable complexes with arrestin2. Crystal structures of arrestin2 in apo form and in complexes with two CCR5 C-terminal phosphopeptides revealed three key CCR5 phosphoresidues in a pXpp motif that form extensive interactions with arrestin2 and lead to activation. The same phosphoresidue-cluster is present in other receptors which form stable complexes with arrestin2. The contributions of each CCR5 phosphoresidue on arrestin2 conformation and binding have been characterized by a combination of NMR spectroscopy, biochemical and functional assays. We propose that the identified pXpp motif is responsible for robust arrestin2 recruitment in many GPCRs. Moreover, an analysis of available sequence, structural and functional information on other GPCR arrestin interactions suggests a particular spatial arrangement of phosphoresidues within the GPCR intracellular loops and C-terminal tail determines arrestin2 and 3 isoform specificity.

Down-regulation of collagen hydroxylation in colorectal liver metastasis

Project description:Collagen, a major component of the extracellular matrix, is significantly upregulated in colorectal liver metastasis (CRLM) compared to liver tissue. Expression levels of specific collagen types in CRLM resemble those in colorectal cancer (CRC) and colon tissue. We investigated whether the collagen hydroxylation pattern from the primary tumor also migrates with the metastatic tumor. The degree of collagen alpha-1(I) hydroxylation in colon, CRC, liver, and CRLM tissue in the same individuals (n=14) was studied with mass spectrometry. The degree of hydroxylation was investigated in 36 collagen alpha-1(I) peptides, which covered 54% of the triple helical region. The average degree of hydroxylation in liver tissue was similar to that in colon tissue. The overall degree of hydroxylation was significantly lower (9% +/- 14%) in CRC tissue and also significantly lower (12% +/-22%) in CRLM tissue compared to colon or liver tissue. Still, in previous research of liver and CRLM enzymes involved in collagen hydroxylation were found to be upregulated, whereas P4HB (4-prolyl hydroxylase beta unit) was downregulated. Furthermore, 11 peptides are present with a specific number of hydroxylations that are significantly different between CRLM and liver tissue; these peptides could be candidates for the detection of CRLM. For one of these eleven peptides, a matching naturally occurring peptide in urine has been identified as being significantly different between patients suffering from CRLM and healthy controls. We conclude that the degree of hydroxylation in CRC and CRLM tumor tissue is in general significantly downregulated in comparison to healthy colon and liver tissue. The hydroxylation pattern in CRLM resemble partly the pattern in liver, primary colorectal cancer and colon.

Transcription profilung of E. coli known to be uropathogenic conditioning to nitrosative stress

Project description:While in transit within and between hosts, uropathogenic E. coli (UPEC) encounter multiple stresses, including substantial levels of nitric oxide and reactive nitrogen intermediates. Strains of UPEC become conditioned to high concentrations of acidified sodium nitrite (ASN), a model system used to generate nitrosative stress. We used microarrays to define the expression profile of UPEC that have been conditioned for growth in ASN. Experiment Overall Design: Separate colonies of the UPEC isolate UTI89 grown on LB agar plates from a -80Â°C freezer stock were used to start overnight shaking cultures in MES-buffered LB broth (MES-LB, pH 5.0). Each culture was then diluted 1:100 into 7 ml MES-LB with or without 3 mM ASN in loosely capped 20-by-150-mm borosilicate glass tubes and grown with shaking at 37Â°C. Growth was monitored by optical density until OD600 = 1.5, at which point cultures were spun down, and pellets frozen at -80Â°C for at least 12 h. RNA was extracted with hot phenol-chloroform and purified by CsCl centrifugation. cDNA was synthesized, fragmented, and labeled for hybridization to Affymetrix GeneChipÂ® E. coli Genome 2.0 Arrays.

Chorioallantoic membrane (CAM) and embryonic blood serum proteomics

Project description:In chickens, embryonic development begins upon egg formation and lasts for 21 days of incubation until hatching. The CAM is an extraembryonic membrane that serves a critical role in acid-base balance, gaseous exchange, calcium solubilization, and antimicrobial protection. Comparative proteomic analyses of CAM at two developmental stages (ED12 and ED19), in comparison to the proteome of embryonic blood serum, revealed protein groups that are relatively or highly specific to the CAM. The specific CAM functions include gaseous exchange, Ca2+ transport, vasculature development, and protection against pathogen invasion. Overall, our results highlight the structure-function relationship of the CAM protein constituents that potentially could expand its biomedical applications.
