| http://www.reactome.org/bio... | biopax3:comment | Nicotinamide levels are modulated by the action of three enzymes involved in nicotinamide salvaging. They are nicotinamide deaminase, nicotinamide phosphoribosyltransferase and nicotinate phosphoribosyltransferase. These enzymes are poorly characterized in humans, depsite their importance in nicotinamide utilization. | lld:biopax3 |
