ProteomicsAnalysis of reconstituted tripartite complex supports avidity-based recruitment of Hsp70 by substrate bound J-domain protein
Hsp70 are ubiquitous, versatile molecular chaperones that cyclically interact with substrate protein(s). The initial step requires synergistic interaction of a substrate and a J-domain protein (JDP) cochaperone, via its J-domain, with Hsp70 to stimulate hydrolysis of its bound ATP. This hydrolysis d...

MetabolomicsMetabolite profiling of Arabidopsis mutants of enzymes of lower glycolysis
We have previously shown that in Arabidopsis the three enzymes of lower glycolysis phosphoglycerate mutase (PGAM), enolase and pyruvate kinase form a complex which play an important role in co-sub-cellar localization the mitochondria to the chloroplast. Given that their metabolites of these mutants,...

ProteomicsMass spectrometric analysis of proteolytic cleavage related to ArtA and PssA from Haloferax volcanii
The S-layer glycoprotein (SLG) of Haloferax volcanii has been shown to be processed and C-terminally linked to a lipid in an archaeosortase A (ArtA)-dependent manner. A C-terminal tripartite structure including a PGF motif is required for the processing of SLG as well as other substrates (Abdul Hali...

ProteomicsSplit-TurboID with Bre5 and Rps2 in Saccharomyces cerevisiae
The in vivo labeling technique Split-Biotin identification (Split-BioID, De Munter et al., 2017, Schopp et al., 2017, Cho et al., 2020) was used to capture the common microenvironment of Bre5 and the ribosomal protein Rps2 (uS5). Biotinylated proteins were enriched from cell lysates using affinity p...

ProteomicsPhosphoproteomics of Jatropha curcas seedling under chilling stress
As a promising energy plant for biodiesel, Jatropha curcas is a tropical and subtropical shrub. Chilling is a major abiotic stress affecting the growth and development of J. curcas. In this study, we adopt the phosphoproteomic analysis, physiological measurement, ultrastructure observation to illust...

ProteomicsAnother layer of complexity in Staphylococcus aureus methionine biosynthesis control: Unusual RNase III-driven T-box riboswitch cleavage determines met operon mRNA stability and decay
In Staphylococcus aureus, de novo methionine biosynthesis is regulated by a unique hierarchical pathway involving stringent-response controlled CodY repression in combination with a T-box riboswitch and RNA decay. The T-box riboswitch residing in the 5' untranslated region (met leader RNA) of the S....

TranscriptomicsGrowth-rate dependency of de novo resveratrol production in chemostat cultures of an engineered Saccharomyces cerevisiae strain
Saccharomyces cerevisiae has become a popular host for production of non-native compounds. The metabolic pathways involved generally require a net input of energy. To maximize the ATP yield on sugar in S. cerevisiae, industrial cultivation is typically performed in aerobic, sugar-limited fed-batch r...

MetabolomicsEvaluation of sample preparation methods for NMR-based metabolomics of cow milk
The quality of milk metabolome analyzed by nuclear magnetic resonance (NMR) is greatly influenced by the way samples are prepared. Although this analytical method is increasingly used to study milk metabolites, a thorough examination of available sample preparation protocols for milk has not been re...

MetabolomicsElevated CO2 and virus infection impacts wheat and aphid metabolism

INTRODUCTION: The aphid Rhopalosiphum padi L. is a vector of Barley yellow dwarf virus (BYDV) in wheat and other economically important cereal crops. Increased atmospheric CO2 has been shown to alter plant growth and metabolism, enhancing BYDV disease in wheat. However, the bioch...
