UvrABC removes 12 nucleotides around a DNA mutation replacing them with the correct one[1]. UvrA is the protein which locates the DNA damage. UvrB is involved in distinguishing damaged from undamaged DNA[2]. The C-terminal region of UvrC is involved in DNA binding and incisions at the 5'-side of a DNA damage during nucleotide excision repair[3]. UvrD is DNA helicase II. See Helicase. For details on the UvrA-UvrB complex see UvrA-UvrB interaction domains. Structural highlights UvrA contains several domains: [4].
