How is Coenzyme A Transported to the Matrix?
Zhyvoloup et al. (2003) J Biol Chem 278: 50316-50321; emphasis mine:


  CoA synthase is localized on the mitochondrial outer membrane.
  Moreover, we demonstrate for the first time that phosphatidylcholine
  and phosphatidylethanolamine, which are the main components of the
  mitochondrial outer membrane, are potent activators of both enzymatic
  activities of CoA synthase in vitro. Taken together, these data
  provide the evidence that the final stages of CoA biosynthesis take
  place on mitochondria and the activity of CoA synthase is regulated by
  phospholipids.
