The Listeria monocytogenes-secreted p60 protein is an N-end rule substrate in the cytosol of infected cells. Implications for major histocompatibility complex class I antigen processing of bacterial proteins.

Abstract excerpt

Cytosolic antigen degradation is an initial step in the generation of major histocompatibility complex (MHC) class I-associated cytolytic T lymphocyte epitopes. Intracellular Listeria monocytogenes secretes p60, a murein hydrolase, into the host cell cytosol, where it is degraded by proteasomes. Roughly 3% of degraded p60 gives rise to p60 217-225, a nonamer peptide that is bound by H-2Kd MHC class I molecules....
