The African trypanosome (Trypanosoma brucei) diverged early from the eukaryotic lineage and is an important parasite of humans and their livestock. Many fundamental molecular and biochemical processes were first discovered in trypanosomes, some ‘unusual’, others broadly conserved. An excellent range…
