| Research Abstract |
Ubiquitinated ActA-deficient Listeria monocytogenes(. actA) were recognized by autophagy. To elucidate the mechanism of Listeria ubiquitination, we attempted to explore the bacterial ubiquitinized molecules and the host ubiquitination factors. As a result, two candidates of bacterial ubiquitinated molecules and four candidates involved in host ubiquitination system were identified by LC-MS/MS analysis. The recombinant proteins of Listeria candidate moleculesexamined by in vitro ubiquitination assay, and one of the two candidates inListeria wa weres received ubiquitination directly.
