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 -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {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. CC {ECO:0000313|EMBL:HIU98947.1}.
