Released:

Function and Biology Details

Reactions catalysed:
(1a) [protein]-N(6)-acetyl-L-lysine + NAD(+) = [protein]-N(6)-(1,1-(5-adenosylyl-alpha-D-ribose-1,2-di-O-yl)ethyl)-L-lysine + nicotinamide
ATP + acetate + CoA = AMP + diphosphate + acetyl-CoA
ATP + propanoate + CoA = AMP + diphosphate + propanoyl-CoA
