ENZYME entry: EC 1.4.7.1

Accepted Name
Glutamate synthase (ferredoxin).
Alternative Name(s)
Ferredoxin-dependent glutamate synthase.
Reaction catalysed
2 L-glutamate + 2 oxidized ferredoxin <=> L-glutamine + 2-oxoglutarate + 2 reduced ferredoxin + 2 H(+)
Cofactor(s)
FAD; FMN; Iron-sulfur.
Comment(s)
  • 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.
