Protein

Serine hydroxymethyltransferase

Gene

glyA

Organism
Coxiella burnetii (strain RSA 493 / Nine Mile phase I)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.UniRule annotation

Catalytic activityi

5,10-methylenetetrahydrofolate + glycine + H2O = tetrahydrofolate + L-serine.UniRule annotation

Cofactori

pyridoxal 5'-phosphateUniRule annotation

Pathwayi: tetrahydrofolate interconversion
