GDH2 — Brassica juncea

Summary

BJUA03G54900S (BjGDH2, GDH2) on chromosome A03 of Indian mustard encodes a glutamate dehydrogenase with NAD(P)+, NAD+, and NADP+ activities, along with co-ion, copper, zinc, and ATP binding capabilities. The protein belongs to the Glu_DH family and is localized to mitochondria, the mitochondrial lumen, cytoplasm, plasmalemma, and plant-type vacuoles. BjGDH2 is associated with glutamate breakdown, response to nitrogen compounds, nitrate, nitrogen starvation, basic pH, cold, salinity, and carbohydrate metabolism. It has been linked to respiration rate, carbon starvation tolerance, chlorophyll degradation, leaf senescence, low-oxygen and anoxia tolerance, redox response, and nitrogen metabolism. Related genes in other species connect the family to aluminum response, stomatal opening, leaf senescence, and reduced growth on glutamate media under darkness.
