Superfamily	Aldolase class I
Functional Family	Ferredoxin-dependent glutamate synthase, chloroplastic

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.
