Ribosylnicotinamide kinase

In enzymology, a ribosylnicotinamide kinase (EC number|2.7.1.22) is an enzyme that catalyzes the chemical reaction

:ATP + N-ribosylnicotinamide $ightleftharpoons$ ADP + nicotinamide ribonucleotide

Thus, the two substrates of this enzyme are ATP and N-ribosylnicotinamide, whereas its two products are ADP and nicotinamide ribonucleotide.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:N-ribosylnicotinamide 5'-phosphotransferase. This enzyme is also called ribosylnicotinamide kinase (phosphorylating). This enzyme participates in nicotinate and nicotinamide metabolism.
