non-identity-mediated crispr-bacteriophage interaction mediated via the csy and cas3 proteins. | studies of the escherichia, neisseria, thermotoga, and mycobacteria clustered regularly interspaced short palindromic repeat (crispr) subtypes have resulted in a model whereby crisprs function as a defense system against bacteriophage infection and conjugative plasmid transfer. in contrast, we previously showed that the yersinia-subtype crispr region of pseudomonas aeruginosa strain ucbpp-pa14 plays no detectable role in viral immunity but instead is required for bacteriophage dms3-dependent inh ... | 2011 | 21398535 |
