| Abstract: | A 10,095 base pair DNA fragment from the right arm of chromosome III of Saccharomyces cerevisiae has been sequenced and analysed. It encompasses the silent mating-type locus HMR. Both HMRa1 and HMRa2 genes, as well as their flanking regulatory regions, have been identified. Three new open reading frames longer than 80 amino acid residues were found in this fragment. One of them (YCR137) shows features compatible with a membranous localization and a transporter function. The other two do not show a similarity with any known gene. A new gene coding for tRNA(thr)al (ACU) has been identified. It is located in a region coding for several delta sequences. |
