    ..By coupling these pathways, cytochrome c and Ccp1 function efficiently as Erv1-dependent electron acceptors. Thus, we propose that Erv1 utilizes diverse pathways for electron shuttling in the IMS. ..

    ..We postulate that Cyc2p, possibly in a complex with CCHL, reduces the haem iron prior to haem attachment to the apoforms of cytochrome c and c(1) . ..

    ..We postulate that, in vivo, Cyc2p interacts with CCHL and is involved in the reduction of heme prior to its ligation to apocytochrome c by CCHL. ..

    ..CC(1)HL-dependent assembly of holocytochrome c(1). We also provide evidence that Cyc2p is dedicated to the CCHL pathway and is not required for the CC(1)HL-dependent assembly of cytochrome c(1). ..
