Proteolytic enzymes from adult Glossina morsitans morsitans, G. m. centralis, G. m. submorsitans, G. palpalis palpalis, and G. p. gambiensis and larvae of G. m. morsitans were separated using DEAE-cellulose chromatography and Sephadex gel-filtration and characterized by their ability to hydrolyse casein and/or synthetic substrates. Adults of G. morsitans sensu lato have seven proteolytic enzymes: trypsin, carboxypeptidase A, carboxypeptidase B, a chymotrypsin-like enzyme (PVII), a trypsin-like enzyme (PVI) and two aminopeptidases B, a chymotrypsin-like enzyme (PVII), a trypsin-like enzyme (PVI) and two aminopeptidases (AP1 and AP2). An additional trypsin-like enzyme, PVIII, was found in adult G. p. palpalis and G. p. gambiensis. PVII was not detected in G. p. palpalis. Homologous enzymes from adults of all taxa have similar chromatographic properties and similar molecular weights. Neither PVI nor PVII were detected in G. m. morsitans larvae; however larvae possess a unique chymotrypsin-like enzyme, PIX.
