Overview

Mode of Action (MoA) None
Evidence Deletion of vcrx089-090 (ECO_0007379) led to a 25-fold decrease in conjugation efficiency to V. cholerae O395 (which has an active type I R-M system). The transfer defect was rescued by deleting the recipient’s hsdR gene, confirming it’s R-M-related. Complementation in recipient cells (not donors) restored transfer efficiency, supporting their function post-DNA entry.
