Function
TSE1_PSEAE Toxin secreted by the H1 type VI (H1-T6SS) secretion system into the periplasm of recipient cells. Degrades peptidoglycan via amidase activity thereby helping itself to compete with other bacteria (PubMed:21776080, PubMed:22931054, PubMed:22813741, PubMed:22700987). To protect itself, the bacterium synthesizes immunity protein Tsi1 that specifically interacts with and inactivates cognate toxin (PubMed:21776080, PubMed:22931054, PubMed:22700987).[1] [2] [3] [4]
