In nucleotide excision repair in E. coli, what is the function of the UvrA/UvrB complex?
Homework Answers
ANSWER:
Nucleotide excision repair (NER):
Is used by all organisms to eliminate DNA lesions.Determined the structure of the Geobacillus stearothermophilus UvrA-UvrB complex the damage-sensor in bacterial NER and a new structure of UvrA. The DNA binding surface of UvrA previously found in an open shape that binds damaged DNA, also exists in a closed groove shape compatible with native DNA.

Photoreactivation is called a direct reversal of DNA damage. Mismatch repair, Nucleotide excision repair and base excision repair correct DNA mismatches and damaged bases, but these systems are not considered direct repair. what two general steps do these indirect repair systems have in common?.
