Photoreactivation in a phrB mutant of Escherichia coli K-12: evidence for the role of a second protein in photorepair.

Photochemistry and photobiology - 1 Dec 1993

Dorrell N, Ahmed A H, Moss S H

Abstract excerpt

In Escherichia coli, the light-dependent repair of pyrimidine dimers in UV-irradiated DNA is now accepted as being due to enzymatic photoreactivation (PR) by a 50 kDa enzyme, photolyase (EC 4.1.99.3). The gene for this enzyme has been mapped at 16.2 min and designated phr. This gene was earlier described as phrB, another locus phrA having been proposed in association with PR. The relevance of the putative phrA...
