EC 2.1.2.1     
Accepted name: glycine hydroxymethyltransferase
Reaction: 5,10-methylenetetrahydrofolate + glycine + H2O = tetrahydrofolate + L-serine

Other name(s): serine aldolase; threonine aldolase; serine hydroxymethylase; serine hydroxymethyltransferase; allothreonine aldolase; L-serine hydroxymethyltransferase; L-threonine aldolase; serine hydroxymethyltransferase; serine transhydroxymethylase
Systematic name: 5,10-methylenetetrahydrofolate:glycine hydroxymethyltransferase
Comments: A pyridoxal-phosphate protein. Also catalyses the reaction of glycine with acetaldehyde to form L-threonine, and with 4-trimethylammoniobutanal to form 3-hydroxy-N6,N6,N6-trimethyl-L-lysine.
