Biochem/physiol Actions

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).

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

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

The micronutrient selenium is present in proteins as selenocysteine (Sec). In eukaryotes and archaea, Sec is formed in a tRNA-dependent conversion of O-phosphoserine (Sep) by O-phosphoseryl-tRNA:selenocysteinyl-tRNA synthase (SepSecS). Here, we present the crystal structure of Methanococcus maripaludis SepSecS complexed with

Several methanogenic archaea lack cysteinyl-transfer RNA (tRNA) synthetase (CysRS), the essential enzyme that provides Cys-tRNA(Cys) for translation in most organisms. Partial purification of the corresponding activity from Methanocaldococcus jannaschii indicated that tRNA(Cys) becomes acylated with O-phosphoserine (Sep) but not with

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are the most common cause of familial Parkinson's disease (PD). Although biochemical studies have shown that certain PD mutations confer elevated kinase activity in vitro on LRRK2, there are no methods
