Surface exclusion by ColV–K94

Abstract
SUMMARY: Measurement of ColEl transfer by ColV2, inE. coliK12, showed that ColV2 specifies a surface exclusion system. This system is different from those specified by Flac, and by ColVBtrpand Rl-19. Like these other two systems, the ColV2 surface exclusion system is subject to inhibition by the appropriate transfer inhibitor, and is not expressed in stationary phase cells.
