Generation of Listeria-derived spliced epitopes LLO291-294/297-304, PlcB189-192/164-167, and PlcB189-191/163-167. (A) Structure of LLO of Listeria monocytogenes with LLO291-294/297-304 highlighted. Proteasome-catalyzed peptide splicing (PCPS) generates the spliced epitope precursor LLO291-294/297-304. This peptide is N-terminally truncated by ERAP1 which results in LLO294/297-304 (24). (B) L. monocytogenes PlcB189-192/164-167 and PlcB189-191/163-167 are generated from the secreted bacterial virulence factor PlcB via reverse cis-PCPS (25).
