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: [5].
