O-Phospho-DL-serine (pSer) is used in the study of non-enzymatic aminophospholipid glycation.
O-Phosphoserine is used in alternative pathways for biosynthesis of cysteine and of selenocysteine (Sec) by tRNA-dependent conversion of O-phosphoserine (Sep) by O-phosphoseryl-tRNA:selenocysteinyl-tRNA synthase (SepSecS).
Reactive oxygen species (ROS) have been characterized as both important signaling molecules and universal stressors that mediate many developmental and physiological responses. So far, details of the transcriptional mechanism of ROS-responsive genes are largely unknown. In the study reported here

The biosynthesis of cysteine is a crucial metabolic pathway supplying a building block for de novo protein synthesis but also a reduced thiol as a component of the oxidative defense mechanisms that appear particularly vital in the dormant state of
Microbes in ecosystems often develop coordinated metabolic interactions. Therefore, understanding metabolic interdependencies between microbes is critical to deciphering ecosystem function. In this study, we sought to deconstruct metabolic interdependencies in organohalide-respiring consortium ACT-3 containing Dehalobacter restrictus using a combination of

Novel-type serine-synthesizing enzymes, termed metal-independent phosphoserine phosphatases (iPSPs), were recently identified and characterized from Hydrogenobacter thermophilus, a chemolithoautotrophic bacterium belonging to the order Aquificales. iPSPs are cofactor-dependent phosphoglycerate mutase (dPGM)-like phosphatases that have significant amino acid sequence similarity to dPGMs

Mitochondrial dynamics is crucial for the regulation of cell homeostasis. Our recent findings suggest that hepatitis C virus (HCV) promotes Parkin-mediated elimination of damaged mitochondria (mitophagy). Here we show that HCV perturbs mitochondrial dynamics by promoting mitochondrial fission followed by
