Abstract:
:A 3.3-kilobase PvuII fragment carrying the PHR1 gene of Saccharomyces cerevisiae has been cloned into an Escherichia coli expression vector and introduced into E. coli strains deficient in DNA photolyase. Complementation of the E. coli phr-1 mutation was observed, strongly suggesting that the yeast PHR1 gene encodes a DNA photolyase.
