a. C, PE/PPEs encoded by complete esx gene cluster; P, PE/PPE encoded by partial esx cluster; I, PE/PPE encoded by isolated pe/ppe pair (see Figure S1).

b. Single peptide for Rv3018A/PE27A mixed with PE13 set.

c. Pool does not include all possible overlapping peptides, some were excluded due to 100% identity.
