Uniprot: A0A037UN90
Description: serine hydroxymethyltransferase
EC number: 2.1.2.1
Annotation score: 3 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity: CATALYTIC ACTIVITY: 5,10-methylenetetrahydrofolate + glycine + H(2)O = tetrahydrofolate + L-serine. {ECO:0000256|HAMAP-Rule:MF_00051}.
Cofactor: COFACTOR: Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326; Evidence={ECO:0000256|HAMAP-Rule:MF_00051, ECO:0000256|PIRSR:PIRSR000412-50};
Enzyme regulation:
Function [CC]: FUNCTION: 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. {ECO:0000256|HAMAP-Rule:MF_00051}.
Pathway: PATHWAY: Amino-acid biosynthesis; glycine biosynthesis; glycine from L-serine: step 1/1. {ECO:0000256|HAMAP-Rule:MF_00051}.; PATHWAY: One-carbon metabolism; tetrahydrofolate interconversion. {ECO:0000256|HAMAP-Rule:MF_00051}.
