“…Aminopeptidases can be categorized on the basis of their substrate specificity (broad or narrow), catalytic mechanism (serine, metallo, cysteine peptidases), cellular location (cytosolic, membrane, and microsomal), and molecular structure [5][6][7][8][9]. Examples of these enzymes are methionine aminopeptidase, arginine aminopeptidase, leucine aminopeptidase, aminopeptidase A, and aminopeptidase P [10][11][12][13][14].…”
