Molecular cloning of chromosome I DNA from Saccharomyces cerevisiae: localization of a repeated sequence containing an acid phosphatase gene near a telomere of chromosome I and chromosome VIII

Abstract

A 17 kb region from near the right end of chromosome I of Saccharomyces cerevisiae was isolated on recombinant lambda bacteriophages. This region contained the PHO11 gene which was located only 3.4 kb from the right end of the chromosome. We found that this region also was repeated approximately 13 kb from the end of the chromosome VIII DNA molecule. The chromosome VIII sequence appears to be a previously unnamed acid phosphatase gene that we propose to call PHO12. Thus, similar to the repeated SUC, MAL, X and Y' sequences, some members of the repeated acid phosphatase gene family also appear near the termini of yeast chromosomes.
