Suppressors of ICR-induced mutations that exhibit behavior similar to bacterial frameshift suppressors have been identified in the yeastSaccharomyces cerevisiae.The yeast suppressors have been divided into two groups. Previous evidence indicated that suppressors of one group (Group II:SUFI, SUF3, SUF4, SUF5andSUF6) represent mutations in the structural genes for glycyl-tRNA's. Suppressors of the other group (Group III:SUF2andSUF7) were less well characterized. Although they suppressed some ICR-revertible mutations, they failed to suppress Group II frameshift mutations. This communication provides a more thorough characterization of the Group III suppressors and describes the isolation and properties of four new suppressors in that group (SUF1, SUF9, SUF10andsuf11).—In our original study, Group III suppressors were isolated as revertants of the Group III mutationshis4-712andhis4-713.All suppressors obtained as ICR-induced revertants of these mutations mapped at theSUF2locus near the centromere of chromosome III. Suppressors mapping at other loci were obtained in this study by analyzing spontaneous and UV-induced revertants of the Group III mutations.SUF2andSUF10suppress both Group IIIhis4mutations, whereasSUF7, SUF8, SUF9andsuf11suppresshis4-713,but nothis4-712.All of the suppressors exceptsuf11are dominant in diploids homozygous forhis4-713.The suppressors fail to suppress representative UAA, UAG and UGA nonsense mutations.—SUP9is linked to the centromere of chromosomeVI, andSUF10is linked to the centromere of chromosomeXIV. A triploid mapping procedure was used to determine the chromosome locations ofSUF7andSUF8.Subsequent standard crosses revealed linkage ofSUF7tocdc5on chromosomeXIIIand linkage ofSUF8tocdcl2andpet3on chromosomeVIII.
