Isolation of omnipotent suppressors in an [eta+] yeast strain.

Genetics - 1 Mar 1990

All-Robyn J A, Kelley-Geraghty D, Griffin E, Brown N, Liebman S W

Abstract excerpt

Omnipotent suppressors decrease translational fidelity and cause misreading of nonsense codons. In the presence of the non-Mendelian factor [eta+], some alleles of previously isolated omnipotent suppressors are lethal. Thus the current search was conducted in an [eta+] strain in an effort to identify new suppressor loci. A new omnipotent suppressor, SUP39, and alleles of sup35, sup45, SUP44 and SUP46 were...
