== 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<ref>PMID:11004168</ref>.<br />
 +
* '''UvrA''' is the protein which locates the DNA damage<ref>PMID:21240268</ref>.<br />
 +
* '''UvrB''' is involved in distinguishing damaged from undamaged DNA<ref>PMID:10946234</ref>.<br />
 +
* 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<ref>PMID:9421501</ref>.
 +
* '''UvrD''' is '''DNA helicase II'''. See [[Helicase]].
