H2O + L-glutamate + NAD(+) = 2-oxoglutarate + H(+) + NADH + NH4(+) H2O + L-glutamate + NADP(+) = 2-oxoglutarate + H(+) + NADPH + NH4(+) Expressed in roots (PubMed:16120687). Expressed ubiquitously in various tissues (PubMed:19430792). Detected in the region of the apical meristem and cortical cells in the tip region and elongation zone of the roots. Slightly induced by NH(4)Cl, NaNO(3) and NH(4)NO(3) (PubMed:16120687). Induced in roots after nitrogen (N-deprivation) deprivation (PubMed:19430792). Belongs to the Glu/Leu/Phe/Val dehydrogenases family.
