Of S. cerevisiae UAA specific suppressors three leucine-insertors have been remaining unmapped. Mapping of them was attempted by using a set of eight strains that contained a total of 60 markers distributing over the entire genome; the markers were about 30 cM apart and they covered about 70% of the genome. Two supressors, SUP28 and SUP33, were localized on the right arm of chromosome XIV and on the left arm of chromosome XI, respectively. The other suppressor, SUP32, was not mapped, but its location was confined to a few regions in the genome. The present result and the previously available informations clearly show that the UAA suppressor loci are dispersedly distributing ovet the entire S. cerevisiae genome.
