ID   1.4.7.1
DE   Glutamate synthase (ferredoxin).
AN   Ferredoxin-dependent glutamate synthase.
CA   2 L-glutamate + 2 oxidized ferredoxin = L-glutamine + 2-oxoglutarate +
CA   2 reduced ferredoxin + 2 H(+).
CF   FAD; FMN; Iron-sulfur.
CC   -!- The protein is composed of two domains, one hydrolyzing L-glutamine
CC       to NH(3) and L-glutamate (cf. EC 3.5.1.2), the other combining the
CC       produced NH(3) with 2-oxoglutarate to produce a second molecule of
CC       L-glutamate.
CC   -!- The NH(3) 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 (5,6).
