ICR-induced frameshift mutations at thehis4locus inSaccharomyces cerevisiaehave been classified into several groups on the basis of their reversion and suppression properties. One group of externally suppressiblehis4mutations, designated Group II, have been shown to contain +1 G:C insertions in glycine codons and are suppressed by any one of five suppressor mutations described previously (SUFI, SUF3, SUF4, SUF5,andSUP6). The suppressor genes are believed to encode glycine tRNAs containing four base anticodons. —-An analysis of spontaneous co-revertants of the Group II frameshift mutationshis4-206andleu2-3has revealed the existence of eleven new Group II-specific suppressor genes (SUF15throughSlJF25). The locations of the new suppressor loci on the yeast genetic map have been determined. —-By comparing the ability or inability of Group II-specific suppressors mapping at 16 different loci to suppress different Group IIhis4mutations, two subclasses of suppressors have been defined. One subclass suppresseshis4-38andhis4-519,which contain the altered four base mRNA codons 5'-GGGU-3' and 5'-GGGG-3', respectively. The other subclass suppresseshis4-38,but fails to suppresshis4-519.The mechanism of tRNAmediated frameshift suppression and the molecular basis for this division of the suppressors into two subclasses is discussed.
