SYNOPSIS. Steady-state oxygen kinetics of Trypanosoma mega reveal the presence of 3 oxidases. These include an oxidase which is sensitive to salicylhydroxamic acid (SHAM) but insensitive to sodium azide. This oxidase could be the L-α glycerophosphate oxidase present in bloodstream trypanosomes. In addition, an oxidase is present which is azide-sensitive but SHAM-insensitive. This oxidase is inhibited by CO and is probably cytochrome aa3. A 3rd oxidase is insensitive to both azide and SHAM but is inhibited by CO and is possibly cytochrome o. Reciprocal plots of T. mega reveal the presence of 2 oxidases that are inhibited by CO. These results are discussed in the light of previous evidence suggesting the presence of several oxidases and a branched electron transport system in T. mega.
