We report the sequence analysis of a 78,601 bp DNA segment on the left arm of chromosome II of Saccharomyces cerevisiae. This 78.6 kb segment spans the region from the start of a subtelomeric Y' element up to the ILS1 gene. It contains 49 open reading frames (ORFs) with more than 100 amino acids length including 14 internal and five overlapping ORFs. The gene density, excluding the internal ORFs, was calculated as one ORF per 2.2 kb. Eight ORFs (PKC1, TyA, TyB, ATP1, ROX3, RPL17a, PET112 and ILS1) correspond to previously characterized genes. ORF YBL0718 was identified as CDC27; YBL0706 as TEL1. Four other ORFs show strong similarities to already known genes. The gene product of YBL0838 is 60% identical to the ribosomal protein RPL32 from rat, mouse and man. YBL0701 encodes a protein with significant similarity to the initiation factor eIF2 associated p67 glycoprotein from rat. Eight ORFs were disrupted and the resulting yeast strains analysed with respect to their phenotype.
