The Recombination Directionality Aspect, Xis, is a DNA bending protein that establishes the results of integrase-mediated site-specific recombination by redesign of higher-order protein-DNA architectures. 1; 2; 3. In lambda, integration needs integrase (Int), the web host integration aspect (IHF), a big (250 bp) site which has both core-type and arm-type integrase binding sites, and a… Continue reading The Recombination Directionality Aspect, Xis, is a DNA bending protein that
