Cardiolipin synthesis during the cell cycle of the yeast Saccharomyces cervisiae

Cardiolipin synthesis was studied during the aerobic synchronous growth of aerobically grown yeast Saccharomyces cerevisiae. The time course of the synthesis was stepwise and the rise in cardiolipin level in cells coincided in time with the increase in cytochrome oxidase activity. This finding supports the notion of discontinuous completion of the inner mitochondrial membrane and hints at a close relation between cardiolipin and cytochrome oxidase activity.
