Fig 2. Class I leader peptides eluted from sHLA-E molecules.

A) Representative annotated MS2 fragment ion spectra for the identified leader peptides from HLA-A*02:01, HLA-B*18:01, and HLA-C*05:01 that were eluted from purified sHLA-E. B) Length distribution of all non-redundant HLA-E ligands identified combined from Mtb infected and uninfected cells. C) Peptide binding motif of nonamer peptide sequences eluted from HLA-E. Motif was generated using Seq2Logo.
