CC -!- FUNCTION: Catalyzes the reversible interconversion of serine and CC glycine with tetrahydrofolate (THF) serving as the one-carbon CC carrier. This reaction serves as the major source of one-carbon CC groups required for the biosynthesis of purines, thymidylate, CC methionine, and other important biomolecules. Also exhibits THF- CC independent aldolase activity toward beta-hydroxyamino acids, CC producing glycine and aldehydes, via a retro-aldol mechanism. CC {ECO:0000255|HAMAP-Rule:MF_00051}. CC -!- CATALYTIC ACTIVITY: 5,10-methylenetetrahydrofolate + glycine + CC H(2)O = tetrahydrofolate + L-serine. {ECO:0000255|HAMAP- CC 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 CC from L-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}.
