Cytosol alanyl aminopeptidase (, arylamidase, aminopolypeptidase, thiol-activated aminopeptidase, human liver aminopeptidase, puromycin-sensitive aminopeptidase, soluble alanyl aminopeptidase, cytosol aminopeptidase III, alanine aminopeptidase) is an enzyme.
This enzyme catalyses the release of an N-terminal amino acid, preferentially alanine, from a wide range of peptides, amides and arylamides.
This puromycin-sensitive enzyme is a Co<small><sup>2+</sup></small>-activated zinc-sialoglycoprotein.
