| Function
UvrABC endonuclease is an E. coli enzyme complex involved in DNA repair. UvrABC removes 12 nucleotides around a DNA mutation replacing them with the correct one[1].
- UvrA is the protein which locates the DNA damage[2].
- UvrB is involved in distinguishing damaged from undamaged DNA[3].
- 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[4].
- 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: UvrB-binding, DNA-binding and two ATP-binding domains[5].
