Abstract
A cloned fragment of Saccharomyces cerevisiae chromosomal DNA carrying the photoreactivation gene (PHR) has been sequenced. The fragment contains a 1695-bp intronless open reading frame (ORF) coding for a polypeptide of 564 amino acids (aa). The phr gene of Escherichia coli was also sequenced, and the sequence is in agreement with the published data. The yeast PHR gene has a G + C content of 36.2%, whereas 53.7% was found for the E. coli gene. Despite the difference in G + C content there is a 35% homology between the deduced aa sequences. This homology suggests that both genes have originated from a common ancestral gene.Entities:
