Photoreversibility of Induced Mutations in a Nonphotoreactivable Strain of Escherichia Coli

Journal Article · · Proceedings of the National Academy of Sciences of the United States of America
A radiation-resistant derivative (strain H/r) of a nonphotoreactivable mutant strain of Escherichia coli was found to be incapable of photoreversing uv- induced mutations to streptomycin resistance, as well as uv killing. Photoreversibility of uv-induced mutations to prototrophy, however, was found to be essentially normal in an argeninerequiring substrain of H/r (H/r30). It was concluded that photoreversal of uv-induced mutations to prototrophy does not require the photoreactivating enzyme.
