Characterization of the rnc-97 mutation of RNAaseIII: a glycine to glutamate substitution increases the requirement for magnesium ions.

Journal of general microbiology - 1 Apr 1993

Davidov Y, Rahat A, Flechner I, Pines O

Abstract excerpt

The rnc-97 mutation of the Escherichia coli double-stranded-RNA-specific ribonuclease III (RNAaseIII) was previously isolated by virtue of the lethal expression of RNAaseIII in Saccharomyces cerevisiae. Here we show that rnc-97 is a single point mutation causing the substitution of glycine 97 by glutamic acid. The mutation eliminates the lethal phenotype of RNAaseIII expression in yeast and reduces fourfold the...
