Cytosol alanyl aminopeptidase (EC 3.4.11.14, arylamidase, aminopolypeptidase, thiol-activated aminopeptidase, human liver aminopeptidase, puromycin-sensitive aminopeptidase, soluble alanyl aminopeptidase, cytosol aminopeptidase III, alanine aminopeptidase) is an enzyme.
[1][2][3] 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 Co2+-activated zinc-sialoglycoprotein.
