the polypeptide compositions of sucrase ( ec 3.2.1.48 ) -- isomaltase ( ec 3.2.1.10 ) , maltase -- glucoamylase ( ec 3.2.1.20 ) lactase ( ec 3.2.1.23 ) -- phlorizin hydrolase ( ec 3.2.1.62 ) , microvillus aminopeptidase and aspartate aminopeptidase ( ec 3.4.11.7 ) synthesized during culture were studied , and some were found to be similar to those of the pro-forms of the enzymes isolated from animals that had had their pancreatic duct disconnected 3 days before being killed .
