We report the sequence of a 30,469 bp long DNA fragment on the left arm of chromosome XV of Saccharomyces cerevisiae. The fragment contains 15 open reading frames (ORFs) of at least 300 bp. Five previously sequenced yeast genes, PHO80, TIR2, SLG1, the gene encoding the subtilisin-like protease III precursor and the gene coding for ATP-dependent permease, are found among these ORFs. By DNA sequence comparison, two ORFs identified previously reported expressed sequence tags from yeast. Of the proteins encoded by the remaining eight ORFs, six show similarities to proteins from different organisms and two lack detectable similarity with any amino acid sequence described in public data banks.
