Elevated mitochondrial RNA in a Chinese hamster mutant deficient in the mitochondrially encoded subunits of NADH dehydrogenase and cytochrome c oxidase.

Abstract excerpt

In a unique Chinese hamster mutant, Gal-32, the mitochondrially encoded subunits of cytochrome c oxidase (CO I, II, III) and NADH dehydrogenase (ND 1-6) are greatly decreased while other mitochondrially synthesized proteins, such as ATPase subunits 6 and 8, are less affected. Pulse-chase experiments with [35S]methionine demonstrated that the reduced amounts of CO I and ND 5 subunits in Gal-32 are not the result...
