Plastidic pathway of serine biosynthesis. Molecular cloning and expression of 3-phosphoserine phosphatase from Arabidopsis thaliana.
In plants, Ser is biosynthesized by two different pathways: a photorespiratory pathway via Gly and a plastidic pathway via the phosphorylated metabolites from 3-phosphoglycerate. In contrast to the better characterization of the photorespiratory pathway at a molecular level, the molecular regulation and significance of the plastidic pathway are not yet well understood. An Arabidopsis thaliana c...
متن کاملSerine Regulates Phosphatidylethanolamine Biosynthesis
The role of serine as a precursor and metabolic regulator for phosphatidylethanolamine biosynthesis in the hamster heart was investigated. Hearts were perfused with 60 p~ [l-SH]ethanolamine in the presence or absence of serine for up to 60 min. Ethanolamine uptake was attenuated by 0.05-10 mM serine in a noncompetitive manner, and the incorporation of labeled ethanolamine into phosphatidylet...
متن کاملA plastidic transporter involved in aliphatic glucosinolate biosynthesis.
The distinctive flavors and anticarcinogenic properties of cruciferous vegetables are largely due to the presence of glucosinolates. These sulfur-rich metabolites are derived from one of several amino acids via three stages: (1) elongation of the amino acid side chain; (2) formation of the core glucosinolate skeleton; and (3) secondary modification of the side chain (reviewed in Grubb and Abel,...
متن کاملPurification of serine racemase: biosynthesis of the neuromodulator D-serine.
High levels of D-serine occur in mammalian brain, where it appears to be an endogenous ligand of the glycine site of N-methyl-D-aspartate receptors. In glial cultures of rat cerebral cortex, D-serine is enriched in type II astrocytes and is released upon stimulation with agonists of non-N-methyl-D-aspartate glutamate receptors. The high levels of D-serine in discrete areas of rat brain imply th...
متن کاملSerine biosynthesis in Desulfovibrio desulfuricans.
Cell-free extracts of Desulfovibrio desulfuricans possess enzymes which catalyze the synthesis of serine from 3-phosphoglycerate via the intermediates phosphohydroxypyruvate and phosphoserine.
