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

The simultaneous diffusion and metabolism of the D- and L-isomers of the aminopeptidase substrate, leucine-p-nitroanilide (LPNA), were examined in vitro in the hamster cheek pouch. L-LPNA was completely hydrolyzed during diffusion across the cheek pouch, whereas D-LPNA crossed the cheek

An aminopeptidase activity capable of hydrolysing leucine 4-nitroanilide and alanine 4-nitroanilide at pH 7.0 was detected in saponin-CaCl2 extracts and homogenates of adult Schistosoma mansoni. The extracts were also capable of acting on synthetic dipeptides at the same pH, preferentially
