Protein: NADP(+)-dependent glutamate dehydrogenase (NADP-GDH) (EC 1.4.1.4) (A3MWK6)
Organism: Pyrobaculum calidifontis (strain DSM 21063 / JCM 11548 / VA1)
Function: Catalyzes the reversible oxidative deamination of L-glutamate to 2-oxoglutarate and ammonia, thereby playing a key role at the intersection of the carbon and nitrogen metabolic pathways. Shows a high preference for NADP(+)/NADPH as the acceptor/donor over NAD(+)/NADH. May function in vivo in the synthetic direction. Also catalyzes at very low rates the oxidative deamination of L-2-aminobutyrate, and the reductive amination of 2-oxovalerate and 2-oxobutyrate.
