Explain the mode of action of ecori
WebEnzymes such as EcoRI or EcoRV find their recognition sites in long DNA molecules by first binding to the DNA anywhere along the chain and then translocating to the recognition site. The transfer seems to occur primarily by multiple rounds of dissociation and reassociation events with the same chain. However, one-dimensional diffusion along the ... WebSep 15, 2001 · The characteristic feature of this mechanism is the substrate assisted catalysis, i.e. a direct role of the DNA substrate itself in the catalytic mechanism. A variant of this mechanism has been proposed for EcoRI recently . Although recruiting a phosphodiester group as the catalytic base might be considered surprising, this function …
