Cloning and characterization of the yeast nuclear gene for subunit 5 of cytochrome oxidase.


The nuclear gene COX5 coding for subunit 5 of cytochrome oxidase has been cloned by transformation of the cox5-1 mutant aE4-238/AL1 with a library of yeast genomic DNA. The recombinant plasmid pG46/ST2 bearing a nuclear DNA insert of 1.17 kilobase pairs restores the ability of cox5 mutants to respire and to synthesize a wild type subunit 5. The COX5 gene… (More)
