What recognizes the presequence on amino acids destined to the mitochondria and how does it send the chain to the mitochondria?

If you're wondering if there's a mitochondrial equivalent to a signal recognition particle, I don't think there is. The presequence interacts directly with the proteins at the outer mitochondrial membrane, but frankly a protein isn't going to have to go very far before it encounters a mitochondrion.
