1. The phosphoglucose isomerases (PGI's) of the bloodstream forms of Trypanosoma brucei and T. vivax have been purified some 150-fold, using cellulose ion-exchange chromatography, gel filtration and isoelectric focussing. 2. The two trypanosome enzymes showed many similarities in kinetic properties, but differed from each other somewhat in thermal stability and in isoelectric point. 3. Both trypanosome enzymes differ from PGI's from other sources in having a higher Ki for the competitive inhibitor 6-phosphogluconate.
