As a novel protein post-translational modification (PTM), lysine succinylation is widely involved in metabolism regulation by altering the activity of catalytic enzymes. Inactivating succinyl-CoA synthetase in Saccharopolyspora erythraea HL3168 E3 was proved significantly inducing the global protein hypersuccinylation. To investigate the effects, succinylome of the mutant strain E3ΔsucC was identified by using a high-resolution mass spectrometry-based proteomics approach. PTMomics analyses sugge ...[more]

Project description:Background: Lysine succinylation of proteins has potential impacts on protein structure and function, which occurred on post-translation level. However, the information about the lysine succinylation of proteins in tea plants is limited. In the present study, the significant signal of succinylation in tea plants was found by western blot. Subsequently, we performed qualitative analyses to globally identify lysine succinylation substrates by using high accuracy nano LC-MS/MS combined with affinity purification. Results: As a result, a total of 142 lysine succinylation sites were identified in 86 proteins. The identified succinylated proteins are involved in various biological processes and a large proportion of the succinylation sites are present on proteins in the primary metabolism pathway, including glyoxylate and dicarboxylate metabolism, the tricarboxylic acid (TCA) cycle and glycine, serine and threonine metabolism. Moreover, 10 new succinylated sites on histones were detected in tea plants either. Conclusions: These results suggested that succinylated proteins in tea plants might play critical regulatory roles in biological processes, especially in the primary metabolism. This study not only globally analysed the functional annotation of lysine succinylation in tea plants, but also provided valuable information for further investigating the functions of lysine succinylation in tea plants.

Project description:Small ruminant morbillivirus (SRMV), formerly named Peste-des-petits ruminanats virus (PPRV), belongs to the genus Morbillivirus genus in the family Paramyxoviridae and leads to a highly contagious disease in small ruminants, especially goats and sheep. Lysine succinylation is a newly identified and conserved modification and plays important roles in host cells response to pathogen infection. Herein, we present the comprehensive analysis of the succinylome of SRMV-infected Vero cell using quantitative proteomics. Overall, we identified 875 succinylated proteins with 2840 succinylation sites. Comparative analysis revealed that 139 down-regulated succinylated proteins with 228 succinylation sites and 38 up-regulated succinylated proteins with 44 succinylation sites were significant succinylated in response to SRMV infection, seven lysine succinylation motifs were identified. Bioinformatics analysis showed that the succinalated proteins mainly participated in in cellular respiration and biosynthetic process. Protein-protein interaction networks of the identified proteins provided further evidence that a variety of ATP synthase subunits and carbon metabolism were modulated by succinylation, the overlapped proteins between succinylation and acetylation are involved in glyoxylate and dicarboxylate metabolism. In summary, this is the first study of the succinylome in SRMV infection, lysine acetylation may have a more important effect than succinylation in PPRV infection. It provides a novel view on investigating the infection mechanism of SRMV.

Project description:Protein lysine succinylation, an emerging protein post-translational modification widespread among microbiology, animals and plants, represents an important regulator of cellular processes. In our study, we took the first succinylation proteome analysis in the seedling leaves of Bd21 to draw a schematic map. With high accuracy nano LC-MS/MS combined with affinity purification, a total of 605 succinylated peptides in 323 proteins were identified and were implicated in various molecular functions and cellular biological processes. More than half (53.4%) of the proteins only have one lysine succinylated site. These identified proteins are involved in a variety of cellular functions such as amino acids transport/metabolism, post-translational modification, translation/ribosomal structure and lipid metabolism, especially energy and carbohydrate metabolism via GO, conservation analysis, protein interaction network and other bioinformatics analysis. Motif-X analysis of the succinylation sites identified fourteen significantly enriched succinylation motifs (-Ksucc-----K-, -Ksucc------G- etc) for the first time in plants and will provide possible succinylation binding locus for future studies. Secondary structure analysis showed that the succinylation sites occurred predominantly in alpha helix and coil structures which similar with acetylation. 155 (59.2%) of the homologous succinylated proteins were also identified in other three species (E. coli, S. cerevisiae and H. sapiens). 119 (45.4%) succinylated proteins and 115 (19%) sites were also to be acetylated at the same time. Our succinylated protein data set provides a promising starting point for further functional analysis of succinylation in B. distachyon, which could facilitate the elucidation of the entire metabolic network in the model monocot plant.

Project description:Background: Lysine succinylation is a newly identified PTM, which exists widely from prokaryotes to eukaryotes and participates in various cellular processes, especially in the metabolic processes. Staphylococcus epidermidis is a commensal bacterium in the skin, which attracts more attention as a pathogen, especially in immunocompromised patients and neonates by attaching to medical devices and forming biofilms. However, the significance of lysine succinylation in proteins of Staphylococcus epidermidis has not been investigated. Materials and methods: Using antibody affinity enrichment followed by LC-MS/MS analysis, we examined the succinylome of Staphylococcus epidermidis (ATCC®12228™). Then, bioinformatics analysis was performed, including Gene Ontology, KEGG enrichment, motif characterization, secondary structure, protein-protein interaction, and BLAST analysis. Results: A total of 1557 succinylated lysine sites in 649 proteins were identified in Staphylococcus epidermidis (ATCC 12228). Among these succinylation proteins, GO annotation showed that proteins related to metabolic processes and binding activity accounted for the most based on the analysis of biological process and molecular function, respectively. KEGG pathway characterization indicated that proteins associated with the glycolysis/ gluconeogenesis, and citrate cycle (TCA cycle) pathway were more likely to be succinylated. Moreover, 13 conserved motifs were identified. The specific motif KsuD was conserved in model prokaryotes and eukaryotes. Succinylated proteins with this motif were highly enriched in the glycolysis/gluconeogenesis pathway. One succinylation site(K144) was identified in S-ribosylhomocysteine lyase, a key enzyme in the quorum sensing system, indicating the regulatory role succinylation may play in bacterial processes. Furthermore, 15 succinyltransferases and 18 desuccinylases(erasers) were predicted in S.epidermidis by BLAST analysis. Conclusions: We performed the first comprehensive profile of succinylation in Staphylococcus epidermidis and illustrated the significant role succinylation may play in energy metabolism, QS system, and other bacterial behaviors. This study may be a fundamental basis to investigate the underlying mechanisms of colonization, virulence, and infection of S. epidermidis, as well as provide a new insight into regulatory effects succinylation may lay on metabolic processes.

Project description:a quantification method was performed based on tandem mass tag (TMT) labeling and antibody based affinity enrichment of succinylated peptides using high accuracy nano-LC-MS/MS, to explore the portential mechanism of succinylation in affecting the pathogenicity of naturally isolated A. flavus strains with different toxin production. Altogether, 1,240 lysine succinylation sites in 768 proteins were identified with 1,103 lysine succinylation sites in 685 proteins quantified. Comparing the levels of succinylated proteins between high and low aflatoxin-producing A. flavus strains, bioinformatics analysis indicated that almost all succinylated proteins located in the aflatoxin biosynthetic pathway were down-regulated, and these succinylations directly affected the synthesis of aflatoxins.

Project description:Oxybenzone (OBZ), one of a broad spectrum of ultraviolet (UV) absorbents, has been proven to be harmful to both plants and animals, while omics analysis of big data at the molecular level is still lacking. Lysine succinylation (Ksuc) is an important posttranslational modification of proteins that plays a crucial role in regulating the metabolic network in organisms under stress. Here, we report the changes in intracellular Ksuc modification in plants under oxybenzone stress. A total of 1276 succinylated sites on 507 proteins were identified. Among these sites, 181 modified proteins were hypersulfinylated/succinylated in OBZ-stressed pakchoi leaves. Differentially succinylated proteins (DSPs) are distributed mainly in the chloroplast, cytoplasm, and mitochondria and are distributed mainly in primary metabolic pathways, such as reactive oxygen species (ROS) scavenging, stress resistance, energy generation and transfer, photosynthetic carbon fixation, glycolysis, and the tricarboxylic acid cycle.

Project description:Histone protein post-translational modifications (PTMs) are significant for gene expression and DNA repair. Here we report the identification and validation of a new type of PTM in histones, lysine succinylation. The identified lysine succinylated histone peptides were verified by MS/MS of synthetic peptides, HPLC co-elution, and isotopic labeling. We identified 13, 7, 10, and 7 histone lysine succinylation sites in HeLa, mouse embryonic fibroblast, Drosophila S2, and Saccharomyces cerevisiae cells, respectively. We demonstrated that this histone PTM is present in all eukaryotic cells we examined. Mutagenesis of succinylation sites followed by functional assays implied that histone lysine succinylation can cause unique functional consequences. We also identified one and two histone lysine malonylation sites in HeLa and S. cerevisiae cells, respectively. Our results therefore increase potential combinatorial diversity of histone PTMs and suggest possible new connections between histone biology and metabolism.
