RESUMO
Recessive lysine-independent revertants were isolated from a ψ+ haploid strain of the yeast Saccharomyces cerevisiae containing one of the leucine-inserting UAA suppressors, SUP29, and various UAA mutations including lys1-1. The majority of the revertants were found to have recessive suppressors in addition to the pre-existing SUP29 mutation. The recessive suppressors were able to suppress only a very limited number of UAA mutations, and none of the UAG mutations thus far examined. The recessive inefficient UAA suppressors were assigned to three complementation groups, sup111, sup112, and sup113. A high incidence of gene conversion was observed for an allele of sup111. An antisuppressor acting on sup111, but not detectably on SUP29, was inadvertently obtained during the course of the study. Interactions between SUP29, sup111 and the antisuppressor asu12 were studied.
