2FE-2S FERREDOXIN FROM SYNECHOCYSTIS SP. PCC 6803

Overview

Glutamate synthases (GltS) are crucial enzymes in ammonia assimilation in, plants and bacteria, where they catalyze the formation of two molecules of, L-glutamate from L-glutamine and 2-oxoglutarate. The plant-type, ferredoxin-dependent GltS and the functionally homologous alpha subunit of, the bacterial NADPH-dependent GltS are complex four-domain monomeric, enzymes of 140-165 kDa belonging to the NH(2)-terminal nucleophile family, of amidotransferases. The enzymes function through the channeling of, ammonia from the N-terminal amidotransferase domain to the FMN-binding, domain. Here, we report the X-ray structure of the Synechocystis, ferredoxin-dependent GltS with the substrate 2-oxoglutarate and the, covalent inhibitor 5-oxo-L-norleucine bound in their physically distinct, active ...
