ABSTRACT Leucine aminopeptidase (LAP) belongs to a family of ubiquitous peptidases, with roles in growth and development, stress responses and adaptation to changing environmental conditions.
8, were incubated overnight at 37[degrees]C with pronase (Calbiochem, EMD Biosciences, San Diego, CA) at 1:100 wt/wt ratio and leucine aminopeptidase (Sigma-Aldrich) at 1:1,000 wt/wt ratio.
By an enzyme-histochemical method, leucine aminopeptidase reactivity was localized principally within the cytoplasm of granulated cells in the buccal cavity, esophagus, esophageal pouch, hepatopancreas, and the third intestinal region, which implies that these sites are responsible for the synthesis and secretion of this peptidase for the digestion of proteinaceous nutrients.
