An N-acylamino acid acylase from Nicotiana tabacum leaves

An N-acylamino acid acylase was partially purified from tobacco (Nicotiana tabacum) leaves and some of its properties are described. It hydrolyses N-acetylarginine, N-acetylmethionine, N-acetylcysteine and to a lesser extent N-formylmethionine. It does not appreciably hydrolyse N-formyl peptides and is therefore unlikely to be involved in protein synthesis.
