Photoreactivation in phr mutants of Escherichia coli k-12: Cloning from the gal-attλ interval increases the photoreactivable response in phrA strains

In this report we have cloned restriction fragments from the gal-attλ region obtained from a purified preparation of λ dgal transducing 'phage DNA, and demonstrate the appearance of a photoreactivable response in a photoreactivation-deficient phrA phrB strain. We also show that when this plasmi...
