NAD+ kinase
NAD+ kinase (EC 2.7.1.23, NADK) is an enzyme that converts nicotinamide adenine dinucleotide (NAD+) into NADP+, through phosphorylating the NAD+ coenzyme.[2] NADP+ is an essential coenzyme in metabolism and provides reducing power to biosynthetic processes such as fatty acid biosynthesis.[3] The structure of the NADK from the archaean Archaeoglobus fulgidus has been determined.[1]
In humans, NAD+ kinase is encoded by the NADK gene.[4]
Reaction
ATP + NAD+ ADP + NADP+
