Abstract excerpt
Recessive lethal mutations in the beta subunit of eIF-2 that restore HIS4 expression in the absence of an AUG start codon were isolated from diploid Saccharomyces cerevisiae strains. DNA sequence analysis of these alleles and of eIF-2 beta suppressor alleles isolated from haploid strains, identified point mutations that altered one of six amino acids that map to a Cys-X2-Cys-X19-Cys-X2-Cys "zinc finger" motif and...
