Notes:
We have sequenced on both strands a 44,019 bp fragment located on the left arm of Saccharomyces cerevisiae chromosome XV.The sequenced segment contains 22 open reading frames (ORFs) of at least 100 amino acids long, one of which probably contains an intron. Six of the 22 ORFs correspond to known proteins: the multicopy suppressor of Snf1 protein 1, the two Ty1-H3 transposon proteins TyA and TyB, the myo-inositol transporter 2, the transcription factor protein Ino4 and the 3,4-dihydroxy-5-hexaprenylbenzoate methyltransferase. Of the 16 remaining ORFs, two show highest homologies with the yeast serine/threonine protein kinase Ste20 and the human tryptophanyl-tRNA synthetase. Eight ORFs show slight similarities with protein sequences described in data banks.DNA sequence comparison reveals also the presence of three known sequences: the Ty1-H3 transposable element, the yeast suf1(+) frameshift suppressor gene for tRNA-Gly and the yeast transfer RNA-Thr-1a. A fourth DNA sequence shows striking identities with the yeast delta elements.The 44,019 bp sequence has been entered in the EMBL data library under Accession Number Z48149.
