Aminopeptidase activities were identified in extracts of kidney, ovotestis, head ganglia, heart and haemolymph of Aplysia californica. These enzyme preparations hydrolysed [3H][Leu]enkephalin at the Try-1-Gly-2 bond as determined by h.p.l.c. analysis of cleavage products. In all these tissues, enkephalin-degrading aminopeptidase

A general method for detecting leucyl aminopeptidase activity after native polyacrylamide gel electrophoresis (PAGE) in situ is described. The method is based on diazotization of p-nitroaniline, liberated in the polyacrylamide gel by leucyl aminopeptidase action on leucine-p-nitroanilide (LpNA) and subsequent
