Function	This enzyme is key enzyme in folate metabolism and can catalyze an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis. And it also slowly reduces folate to 5,6,7,8-tetrahydrofolate.
KEGG Pathway	Folate biosynthesis (ecj00790 ) Metabolic pathways (ecj01100 ) One carbon pool by folate (ecj00670 )
