CC -!- FUNCTION: Catalyzes the reversible interconversion of serine and
CC glycine with tetrahydrofolate (THF) serving as the one-carbon carrier.
CC This reaction serves as the major source of one-carbon groups required
CC for the biosynthesis of purines, thymidylate, methionine, and other
CC important biomolecules. Also exhibits THF-independent aldolase activity
CC toward beta-hydroxyamino acids, producing glycine and aldehydes, via a
CC retro-aldol mechanism. {ECO:0000256|HAMAP-Rule:MF_00051}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + glycine + H2O =
CC (6S)-5,6,7,8-tetrahydrofolate + L-serine; Xref=Rhea:RHEA:15481,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15636, ChEBI:CHEBI:33384,
CC ChEBI:CHEBI:57305, ChEBI:CHEBI:57453; EC=2.1.2.1;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00051};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|HAMAP-Rule:MF_00051, ECO:0000256|PIRSR:PIRSR000412-50};
CC -!- PATHWAY: Amino-acid biosynthesis; glycine biosynthesis; glycine from L-
CC serine: step 1/1. {ECO:0000256|HAMAP-Rule:MF_00051}.
CC -!- PATHWAY: One-carbon metabolism; tetrahydrofolate interconversion.
CC {ECO:0000256|HAMAP-Rule:MF_00051}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_00051}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00051}.
CC -!- SIMILARITY: Belongs to the SHMT family. {ECO:0000256|ARBA:ARBA00006376,
CC ECO:0000256|HAMAP-Rule:MF_00051}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
