>gnl|CDD|153147 cd04875, ACT_F4HF-DF, N-terminal ACT domain of formyltetrahydrofolate deformylase (F4HF-DF; formyltetrahydrofolate hydrolase). This CD includes the N-terminal ACT domain of formyltetrahydrofolate deformylase (F4HF-DF; formyltetrahydrofolate hydrolase) which catalyzes the hydrolysis of 10-formyltetrahydrofolate (formyl-FH4) to FH4 and formate. Formyl-FH4 hydrolase generates the formate that is used by purT-encoded 5'-phosphoribosylglycinamide transformylase for step three of de novo purine nucleotide synthesis. Formyl-FH4 hydrolase, a hexamer which is activated by methionine and inhibited by glycine, is proposed to regulate the balance FH4 and C1-FH4 in response to changing growth conditions. Members of this CD belong to the superfamily of ACT regulatory domains. Length = 74
