title: Antimitotics induce cardiolipin cluster formation. Possible role in mitochondrial enzyme inactivation.
abstract: We demonstrate here that drugs which inactivate cytochrome c oxidase are able to segregate cardiolipin essential for the enzyme activity, in a separate phase inaccessible for the enzyme. A molecular explanation of the drug-induced aggregation process is proposed.
