Enzyme Commission Summary:
This enzyme catalyzes release of an N-terminal amino acid, preferentially alanine, from a wide range of peptides, amides and arylamides.
A puromycin-sensitive, Co2+-activated zinc-sialoglycoprotein that is generally cytosolic. Multiple forms are widely distributed in mammalian tissues and body fluids. In peptidase family M1 (membrane alanyl aminopeptidase family).
