GONUTS is under stress! The website is currently experiencing long-wait times and frequent time-outs due to the record number of students, groups, and annotations related to CACAO this semester. We are currently working on increasing performance -- please accept our apologies for the technical difficulties.
You can help reduce stress on the server by:
- not reloading pages frequently - this just adds
- opening links in new windows (so you can read the old page)
Category:GO:0009380 ! excinuclease repair complex
name: excinuclease repair complex
namespace: cellular_component
def: "Any of the protein complexes formed by the UvrABC excinuclease system, which carries out nucleotide excision repair. Three different complexes are formed by the 3 proteins as they proceed through the excision repair process. First a complex consisting of two A subunits and one B subunit bind DNA and unwind it around the damaged site. Then, the A subunits disassociate leaving behind a stable complex between subunit B and DNA. Now, subunit C binds to this B+DNA complex and causes subunit B to nick the DNA on one side of the complex while subunit C nicks the DNA on the other side of the complex. DNA polymerase I and DNA ligase can then repair the resulting gap." [GOC:mah, GOC:mlg, PMID:15192705]
