Physiological function[]

At1g29930.1/Function_____________The entry below does not belong to this gene_________________ ___________________________ ____________________ ___________ __________ __________________ __________________ _________________ _________________ ______________ ________________ (At1g78590) NADK3 (At1g78590) is a NAD(H) kinase with a strong preference for NADH over NAD+. NAD(H) kinases phosphorylate NAD(H) with ATP (other phosphoryl donors are not used preferentially) to form NADP(H). Phosphorylation of NAD(H) is the sole known means of generating NADP(H) de novo.
