Enzyme Information
| 1.4.7.1 |
Glutamate synthase (ferredoxin).
based on mapping to UniProt P55038
2 L-glutamate + 2 oxidized ferredoxin = L-glutamine + 2-oxoglutarate + 2 reduced ferredoxin + 2 H(+).
-!- The protein is composed of two domains, one hydrolyzing L-glutamine to NH(3) and L-glutamate (cf. EC 3.5.1.2), the other combining the produced NH(3) with 2-oxoglutarate to produce a second molecule of L-glutamate. -!- The NH(3) is channeled through a 24 A channel in the active protein. -!- No hydrolysis of glutamine takes place without ferredoxin and 2-oxoglutarate being bound to the protein.
