Abstract:
:Of 24 bacterial species examined for lisinopril refractive peptidyl dipeptidase activity, only 8 contained activity. Activity in Pseudomonas maltophilia was more than fourfold higher than that of any other species. Pseudomonas maltophilia may be unique among bacteria in possessing high peptidyl dipeptidase activity that is both EDTA inhibitable and lisinopril resistant.
