NAD+ kinase

NAD+ kinase (EC 2.7.1.23, NADK) is an enzyme that converts is_associated_with::nicotinamide adenine dinucleotide (NAD+) into NADP+, through phosphorylating the NAD+ is_associated_with::coenzyme. NADP+ is an essential coenzyme in is_associated_with::metabolism and provides reducing power to biosynthetic processes such as is_associated_with::fatty acid biosynthesis. The structure of the NADK from the is_associated_with::archaean Archaeoglobus fulgidus has been determined.

In humans, NAD+ kinase is encoded by the NADK is_associated_with::gene.

Reaction
ATP + NAD+ $$\rightleftharpoons$$ ADP + NADP+
