Lysosomal and non-lysosomal peptidyl hydrolases of the bloodstream forms of Trypanosoma brucei brucei por Lonsdale-Eccles, John D., Grab, D.J.

“…The serum of some species of animal (e.g. goat and guinea pig) appear to lack the ability to generate this new and increased activity, while rat, rabbit, human and bovine sera exhibit varying capacities to generate the new activity, the cow being the most effective. The apparent molecular masses of the new bands of activity are different for each mammalian species, suggesting that the activator is a species‐specific molecule or class of molecules.We also show that Trypansosoma brucei contains soluble peptidolytic activity with an alkaline pH optimum. …”
