nicotinamide
-
inhibition of the cyclization reaction and is 30fold more potent at suppressing the base-exchange reaction. Inhibition is not via a competition with the nicotinic acid-binding site
additional information
-
the cyclization reaction is insensitive to free Ca2+ concentration in the range 20 nM–100 microM. Mg2+ is not inhibitory
