CC -!- FUNCTION: Catalyzes the reversible interconversion of serine and
CC glycine with a modified folate serving as the one-carbon carrier. Also
CC exhibits a pteridine-independent aldolase activity toward beta-
CC hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol
CC mechanism. {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: 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}.
