| Description: A complex of A and B proteins tracks along DNA until it reaches a thymine dimer or other damaged site, where it halts and forces the DNA to bend. UvrA (a “molecular matchmaker”) then dissociates, allowing UvrC to bind to B. The BC complex cuts on both sides of the dimer. Helicase, polymerase, and ligase remove the damaged undecamer and replace it with new DNA. This system may use DNA polymerase II as well as pol I.
