although a wide range of aminoacyl-7-amino-4-methylcoumarin derivatives ( which are used to measure aminopeptidase activity ) were hydrolysed by normal human cortical soluble extract , fractionation of the latter via anion exchange and gel filtration chromatography resolved only 4 separable aminopeptidase types ( activity relative to alanyl aminopeptidase in parenthesis ) : alanyl ( ec 3.4.11.14 , 100 % ) ;
C0002570
aminopeptidase
