Protein intrinsic disorder in the acetylome of intracellular and extracellular Toxoplasma gondii.

ABSTRACT: Toxoplasma gondii is an obligate intracellular parasite of the phylum Apicomplexa, which includes a number of species of medical and veterinary importance. Inhibitors of lysine deacetylases (KDACs) exhibit potent antiparasitic activity, suggesting that interference with lysine acetylation pathways holds promise for future drug targeting. Using high resolution LC-MS/MS to identify parasite peptides enriched by immunopurification with acetyl-lysine antibody, we recently produced an acetylome of the proliferative intracellular stage of Toxoplasma. In this study, we used similar approaches to greatly expand the Toxoplasma acetylome by identifying acetylated proteins in non-replicating extracellular tachyzoites. The functional breakdown of acetylated proteins in extracellular parasites is simil
