ID 1.4.7.1 DE glutamate synthase (ferredoxin). AN ferredoxin-dependent glutamate synthase. CA 2 L-glutamate + 2 oxidized [2Fe-2S]-[ferredoxin] = 2-oxoglutarate + CA 2 H(+) + L-glutamine + 2 reduced [2Fe-2S]-[ferredoxin]. CC -!- The protein is composed of two domains, one hydrolyzing L-glutamine CC to NH3 and L-glutamate (cf. EC 3.5.1.2), the other combining the CC produced NH3 with 2-oxoglutarate to produce a second molecule of CC L-glutamate. CC -!- The NH3 is channeled through a 24 A channel in the active protein. CC -!- No hydrolysis of glutamine takes place without ferredoxin and CC 2-oxoglutarate being bound to the protein.
