question: In which types of DNA repair is the UvrAB complex involved?
answer: UvrB and the lesion-recognition factor UvrA form the UvrAB complex, which plays a key role in bacterial nucleotide excision repair (NER). In transcription-coupled repair (TCR), the transcription repair coupling factor Mfd recruits uvrA, and the assembled UvrAB complex initiates repair. UvrAB complex also suppresses illegitimate recombination.
