Glutamate formiminotransferase
Introduction
Glutamate formimidoyltransferase is a methyltransferase enzyme which uses tetrahydrofolate as part of histidine catabolism. It catalyses two reactions:
- 5-formimidoyltetrahydrofolate + L-glutamate <=> tetrahydrofolate + N-formimidoyl-L-glutamate
- 5-formyltetrahydrofolate + L-glutamate <=> tetrahydrofolate + N-formyl-L-glutamate
It is classified under EC 2.1.2.5 and in mammals is found as part of a bifunctional enzyme that also has formimidoyltetrahydrofolate cyclodeaminase activity.[1]
