Proteasome mutants, pre4-2 and ump1-2, suppress the essential function but not the mitochondrial RNase P function of the Saccharomyces cerevisiae gene RPM2.

Genetics - 1 Mar 2000

Lutz M S, Ellis S R, Martin N C

Abstract excerpt

The Saccharomyces cerevisiae nuclear gene RPM2 encodes a component of the mitochondrial tRNA-processing enzyme RNase P. Cells grown on fermentable carbon sources do not require mitochondrial tRNA processing activity, but still require RPM2, indicating an additional function for the Rpm2 protein. RPM2-null cells arrest after 25 generations on fermentable media. Spontaneous mutations that suppress arrest occur with...
