IntEnz Enzyme Nomenclature
EC 2.1.2.1

Names

Accepted name:
glycine hydroxymethyltransferase
Other names:
L-serine hydroxymethyltransferase
L-threonine aldolase
allothreonine aldolase
serine aldolase
serine hydroxymethylase
serine hydroxymethyltransferase
serine transhydroxymethylase
threonine aldolase
Systematic name:
5,10-methylenetetrahydrofolate:glycine hydroxymethyltransferase

Reaction

Cofactor

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.
