Dataset Summary
TitleQuantitative proteomic map of the trypanosomatid Strigomonas culicis: the biological contribution of its endosymbiotic bacterium
DescriptionStrigomonas culicis is a kinetoplastid parasite of insects that maintains a mutualistic association with an intracellular symbiotic bacterium, that is highly integrated into the protozoa metabolism: it furnishes essential compounds and divides in synchrony with the nuclear host. The protozoa, conversely, can be rid of the endosymbiont, producing a cured cell line, which presents a diminished ability to colonize the insect host. This obligatory association can represent an intermediate step of the evolution towards the formation of a organelle, therefore representing an interesting model to understand the symbiogenesis theory. Here, we used shotgun proteomics to compare the S. culicis endosymbiont-containing and aposymbiotic strains, revealing a total of 11,305 peptides, and up to 2,213 proteins (2,029 and 1,452 for wild and aposymbiotic, respectively). Gene ontology associated to comparative analysis between both strains revealed that the biological processes most affected by the elimination of the symbiont were the amino acid metabolism, as well as protein synthesis and folding. This large-scale comparison of the protein expression in S. culicis marks a step forward in the comprehension of the role of endosymbiotic bacterium in monoxenic trypanosomatid biology, particularly because these organisms have a polycistronic open reading frame organization and post-transcriptional gene regulation.
