Cytosolic serine hydroxymethyltransferase catalyzes the reversible reaction of tetrahydrofolate polyglutamate (THF polyglutamate) and serine to form 5,10-methyleneTHF polyglutamate and glycine. The active form of the enzyme is a tetramer (Renwick et al. 1998). In the body, this reaction is a major source of 5,10-methyleneTHF, which in turn is a critical precursor in the synthesis of dTMP.
