GDH — Brassica juncea

Summary

BJUA06G39910S (GDH) on Indian mustard chromosome A06 encodes a glutamate dehydrogenase with both NAD⁺- and NADP⁺-dependent L-glutamate dehydrogenase activity. The product belongs to the Glu/Leu/Phe/Val/Trp dehydrogenase family and contains NAD(P)-binding and dimerisation domains. This gene is associated with glutamate breakdown, proline metabolism, amino acid metabolic processes, and responses to nitrogen compounds, nitrogen starvation, basic pH, cold, and salinity. It is linked to mitochondria and cytosol localisation. Associations with drought tolerance and proline content have been noted. Studies of related genes in other species connect the family to glutamate dehydrogenase (NADP⁺) activity and EC numbers 1.4.1.3 and 1.4.1.4, as well as reproductive growth time.
