Alanyl aminopeptidase ( APN ) is a surface - bound metallopeptidase
that oxidoreductasemediated modulations of the cell surface thiol status affect the enzymatic activity of APN .
Alanyl aminopeptidase ( APN ) is a surface - bound metallopeptidase that processes the N - terminals of biologically active peptides such as enkephalins , angiotensins , neurokinins , and cytokines .
We show here that oxidoreductasemediated modulations of the cell surface thiol status affect the enzymatic activity of APN .
