An antisuppressor that acts on omnipotent suppressors in yeast.

Six partially dominant antisuppressors were obtained that reduce the efficiency of two omnipotent yeast suppressors, sup45 and sup35, thought to be ribosomal ambiguity mutations. Each of these six antisuppressors was shown to fall within a single Mendelian locus, named asu9. The asu9 mutations are specific for omnipotent suppressors; they have no effect on several dominant tRNA-like suppressors...

Interaction of UAG suppressors and omnipotent suppressors in Saccharomyces cerevisiae.

Haploids bearing the dominant UAG suppressor, SUP7-a, and various alleles of the omnipotent suppressor sup35 were examined. The presence of the UAG suppressor reduced the efficiency of some alleles of sup35, and caused other sup35 alleles to be lethal. A nonclassical interaction of the dominant suppressor tRNA and the ribosome is proposed to explain these observations.

Suppressors of yeast actin mutations.

Suppressors of a temperature-sensitive mutation (act1-1) in the single actin gene of Saccharomyces cerevisiae were selected that had simultaneously acquired a cold-sensitive growth phenotype. Five genes, called SAC (suppressor of actin) were defined by complementation tests; both suppression and cold-sensitive phenotypes were recessive. Three of the genes (SAC1, SAC2 and SAC3) were subjected to...

Temperature-sensitive nonsense suppressors in yeast.

A single mutation leads to temperature-sensitive amber and ochre suppression in yeast. This mutation maps in or near the SUP4 gene on chromosome X.

Recessive lethal amber suppressors in yeast.

Recessive lethal amber suppressor mutations have been isolated in a diploid strain of Saccharomyces cerevisiae. Diploids carrying these suppressors upon sporulation yield asci with only two live spores, both lacking the suppressor. At least two classes of recessive lethal suppressors exist. Aneuploid strains carrying one wild type and one suppressor locus have been isolated and used in mapping ...
