L. tarentolae proteins were identified by mass spectroscopy as described in Materials and Methods. Each protein is described by its accession number (http://www.genedb.org), annotation, T. brucei homolog, numbers of peptides, other purifications revealing the same protein, and reference. Proteins were grouped into splicing factors, mRNA metabolism, ribosomal biogenesis and assembly proteins, helicases, and hypothetical proteins. The e-value reflects the probability of identification of the protein by MS data.
