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.
一个携带光复活基因（PHR）的酿酒酵母染色体DNA克隆片段已被测序。该片段包含一个1695碱基对的无内含子开放阅读框（ORF），编码一个由564个氨基酸（aa）组成的多肽。大肠杆菌的phr基因也已测序，其序列与已发表的数据一致。酵母PHR基因的G + C含量为36.2%，而大肠杆菌基因的G + C含量为53.7%。尽管G + C含量存在差异，但推导的氨基酸序列之间有35%的同源性。这种同源性表明这两个基因起源于一个共同的祖先基因。
