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:0000255|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:0000255|HAMAP-Rule:MF_00051};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00051};
CC   -!- PATHWAY: One-carbon metabolism; tetrahydrofolate interconversion.
CC       {ECO:0000255|HAMAP-Rule:MF_00051}.
CC   -!- PATHWAY: Amino-acid biosynthesis; glycine biosynthesis; glycine from L-
CC       serine: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00051}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00051}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00051}.
CC   -!- SIMILARITY: Belongs to the SHMT family. {ECO:0000255|HAMAP-
CC       Rule:MF_00051}.
