对酿酒酵母111号染色体右臂10,095个碱基对的DNA片段进行了测序和分析。它包含沉默的交配型基因座HMR。HMRa1和HMRa2基因及其两侧的调控区都已被确定。在该片段中发现了3个新的长于80个氨基酸残基的开放阅读框。其中一个(YCR137型)显示了与膜定位和转运蛋白功能兼容的特征。另外两个没有显示出与任何已知基因的相似性。一个编码tRNAthral(ACU)的新基因已经被发现。它位于编码几个增量序列的区域中。
A 10,095 base pair DNA fragment from the right arm of chromosome 111 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 (YCRl37) 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 tRNAthral (ACU) has been identified. It is located in a region coding for several delta sequences.
