Notes:
We have determined the complete nucleotide sequence of a 12·5 kb segment from the right arm of chromosome II carried by the cosmid α20. The sequence encodes the 5′ end of the IRA1 gene. Two complete new open reading frames and the 3′ non-coding region of the SUP1 (SUP45) gene. A comparison of our sequence with the data bank reveals a 154 amino acid extension at the N-terminus of Ira1p compared to the previously predicted sequence. According to the 11th edition of the Saccharomyces cerevisiae genetic map, our sequence should encode the MAK5 gene, which is necessary for the maintenance of dsRNA killer plasmids. One of the two new open reading frames, YBR1119, is predicted to encode an RNA helicase, thus YBR1119 may correspond to the MAK5 gene. The sequence has been deposited in the EMBL data library under Accession Number X78937.
