A comprehensive analysis of Trypanosoma brucei mitochondrial proteome.

ABSTRACT: The composition of the large, single, mitochondrion (mt) of Trypanosoma brucei was characterized by MS (2-D LC-MS/MS and gel-LC-MS/MS) analyses. A total of 2897 proteins representing a substantial proportion of procyclic form cellular proteome were identified, which confirmed the validity of the vast majority of gene predictions. The data also showed that the genes annotated as hypothetical (species specific) were overpredicted and that virtually all genes annotated as hypothetical, unlikely are not expressed. By comparing the MS data with genome sequence, 40 genes were identified that were not previously predicted. The data are placed in a publicly available web-based database (www.TrypsProteome.org). The total mitochondrial proteome is estimated at 1008 proteins, with 401, 196, and 283 a
