Abstract excerpt
A temperature-sensitive (ts) mutant retains the function of a gene at a low (permissive) temperature but not at a high (nonpermissive) temperature. Arg-DHFR, a dihydrofolate reductase bearing an amino-terminal (N-terminal) arginine, is long-lived in the yeast Saccharomyces cerevisiae, even though arginine is a destabilizing residue in the N-end rule of protein degradation. A ts derivative of Arg-DHFR was...
