This family consists of several bacterial proteins which are closely related to NAD-glutamate dehydrogenase found in Streptomyces clavuligerus. Glutamate dehydrogenases (GDHs) are a broadly distributed group of enzymes that catalyze the reversible oxidative deamination of glutamate to ketoglutarate and ammonia.
