If the XbaI recognition site is preceded by GA or followed by TC, the Dam methylase within most E. coli cloning strains will methylate the GATC site. For example, XbaI sites gaTˆCTAGA and TˆCTAGAtc will be blocked by methylation. To avoid dam methylation use a dam-deficient strain such as dam ...
WebDam methylation is not essential for viability of E. coli ; however, recent data indicate that Dam is an essential gene in Vibrio cholerae and Yersinia pseudotuberculosis (31, 45), similar to results showing that the CcrM methylase is essential in Caulobacter crescentus, Brucella abortus, Rhizobium meliloti, and Agrobacterium tumefaciens (32 ...

WebThe DNA adenine methylase (Dam) system has been increasingly linked to virulence in several bacterial species. Dam methylates the position N6 of adenines in 5′-GATC-3′ sequences, and shapes several processes including DNA replication, chromosome segregation, gene transcription, transposition, and repair. Methylation of the adenine …
