The sequence of a 13 kbp fragment located in the vicinity of the left telomere of chromosome XV (cosmid pEOA179) has been determined. Seven new open reading frames (ORFs) encoding polypeptides longer than 100 residues have been found (AOB629, AOA342, AOC231, AOE555, AOE236, AOA236 and AOE1045). Three of them show no identity with proteins deposited in the data banks. ORF AOB629 (629 amino acids) has some similarity with previously described ferric reductases from Saccharomyces cerevisiae and Schizosaccharomyces pombe. ORF AOA342 encodes a polypeptide reminiscent of dihydroflavonol‐4‐reductases from a number of plant species. AOE236 displays a high level of identity when compared with peroxisomal membrane proteins previously cloned from the methylotrophic yeast Candida boidinii. Finally, AOE1045 encodes a large protein (1045 residues) with some identity with a hypothetical 147 kDa protein identified during the sequencing of Caenorhabditis elegans chromosome 3. The complete nucleotide sequence of the 13 kbp fragment has been deposited at the EMBL data base (Accession Number Z48239). Copyright © 1995 John Wiley & Sons Ltd.
