Short Communication


By the use of a mutation, hxB-20, that eliminates purine hydroxylase II activity but retains cross-reacting material and an ancillary NADH dehydrogenase activity, it has been established that 6-hydroxynicotinic acid rather than nicotinic acid, is the true inducer of purine hydroxylase II.
