The peroxisomal importing translocon with receptors: Pex5p and Pex7p; and receptor facilitator: Pex4p. Peroxisomal biogenesis factor PEX26 is a membrane anchor for the multi-subunit PEX1-PEX6 protein complex that controls ubiquitination and dislocation of PEX5 cargo receptors for peroxisomal matrix protein import. PEX26 associates with the peroxisomal translocation pore via PEX14 (Guder et al. 2018).

Glycosomal membrane protein insertion apparatus.  Two proteins included in the system are PEX14 and PEX19 which target to the peroxisome in several other organisms, but in T. brucei, they target to the glycosome.  By contrast, PEX10 and PEX12 are involved in targetting to the peroxisome (Saveria et al. 2007). Altogether, PEX1, 2, 5, 6, 10, 11, 12, 14, 16, and 19 have been identified in T. brucei and are listed here. Inhibitors of PEX14 block protein import into glycosomes and kill Trypanosma parasites (Dawidowski et al. 2017).
