Abstract

Exogenous methionine enkephalin incubated with CD4⁺ or CD8⁺ T cells purified from murine spleen is metabolized primarily, if not exclusively, by aminopeptidase N (aminopeptidase M, EC 3.4.11.2), a membrane-anchored ectopeptidase. The enzyme activity is identified by its substrate specificity, sensitivity to inhibition by amastatin, and immunoreactivity with antibody to rat kidney aminopeptidase N. Activation of CD4⁺ T cells results in a small increase per cell in aminopeptidase N activity.
