GDH2 — Brassica juncea
Summary
BjGDH2 (GDH2) on chromosome B08 of Indian mustard (Brassica juncea) encodes a glutamate dehydrogenase with NAD(P)+ activity, also annotated for NAD+ and NADP+ specific activities, and binds cofactors including zinc, copper, and ATP. The gene is associated with glutamate breakdown, response to nitrogen compounds, nitrate, nitrogen starvation, basic pH, cold, and salinity, as well as carbohydrate metabolism. It is linked to mitochondrial, vacuolar, plasma membrane, and cytoplasmic localisation. Associations include respiration rate, carbon starvation tolerance, chlorophyll degradation, leaf senescence, low-oxygen and anoxia tolerance, nitrogen metabolism, and redox response. Studies of related genes in other species link the family to aluminum resistance, reduced growth on glutamate media, and stomatal opening.
