• The product of the Saccharomyces cerevisiae CDC8 gene is essential for normal cellular DNA replication; the determination of the structure of the gene and the identification of its product would facilitate the examination of its role in this process. We have cloned a 1,000-base-pair fragment of the S. cerevisiae genome carrying the functional gene. The nucleotide sequence includes one long open reading frame; it is flanked by sequences typical of other S. cerevisiae genes. This sequence predicts a polypeptide chain product of 216 amino acids with a molecular weight of 24,600. A polyadenylated RNA transcript of this sequence was identified by hybridization; in vitro translation of RNA samples enriched for this transcript produced a specific polypeptide chain of apparent molecular weight between 24,000 and 25,000. Thus the reading frame identified represents the authentic CDC8 gene, and the amino acid sequence of its product has been deduced. Our observations differ from two previous reports of the identification of the putative CDC8 protein based upon in vitro complementation assays.
