Mitochondrial import of subunit Va of cytochrome c oxidase characterized with yeast mutants.

The Journal of biological chemistry - 24 Feb 1995

Abstract excerpt

We have investigated the unusual import pathway of cytochrome c oxidase subunit Va (COXVa) into the yeast mitochondrial inner membrane by use of mutants that lack import receptors or are defective in matrix hsp70. (i) Mitochondria lacking the receptor MOM72 are not impaired in import of COXVa. Mitochondria lacking the main receptor MOM19 are moderately reduced in import of COXVa; this, however, is caused by a...
