The data show the total unique peptide counts from two independent purification and mass spectrometry experiments for PF_MetRS-TAP, BF_ProRS-TAP, and BF_MCP2-TAP, three experiments for BF_MetRS-TAP, and one experiment for PF_MCP2-TAP and BF_IleRS-TAP. Peptides that were identified more than once in two or more experiments were only counted once. BF, bloodstream forms; PF, procyclic forms.
The CBP tag is part of the TAP tag and remains associated with the tagged protein after TEV protease digestion.
