although a wide range of aminoacyl-7-amino-4-methylcoumarin derivatives ( which are used to measure aminopeptidase activity ) were found to be hydrolysed by human skeletal muscle soluble fraction , fractionation of the latter via anion-exchange and gel-filtration chromatography resolved only five types of separable aminopeptidase ( with activity relative to alanyl aminopeptidase in parentheses ) : alanyl aminopeptidase ( alpha-aminoacyl-peptide hydrolase , ec 3.4.11.14 , 100 % ) , arginyl aminopeptidase ( two isoenzymes , l-arginyl-l-lysyl ) -peptide hydrolase , ec 3.4.11.6 , 15 % ) ;
