The glycosomes of the Kinetoplastida

Glycosomes are the microbodies of the organisms belonging to the order of the Kinetoplastida, comprising trypanosomes and leishmanias, both pathogens to man. The organelles sequester a number of glycolytic enzymes that are normally located in the cytosol in other eukaryotic organisms, and share some enzymes with peroxisomes and glyoxysomes of other protists, plants and animals. Proteins enter the glycosome by a mechanism of post-translational translocation which involves in some, but not all, cases a C-terminal oligopeptide sequence.
