== Function ==
 +
[https://www.uniprot.org/uniprot/CCP_ECOLI CCP_ECOLI] Cytochrome peroxidase that enables anaerobic respiration with H(2)O(2) as a terminal electron acceptor (PubMed:28696311). It receives electrons from the quinol pool (PubMed:28696311, PubMed:29550214). Menaquinol is probably the electron donor in vivo (PubMed:28696311, PubMed:29550214). It can use menadiol (a menaquinol analog), hydroquinone, duroquinol and the artificial electron donor ABTS(2-) in vitro, but only menadiol and hydroquinone can efficiently transfer electrons to Ccp, maintaining the catalytic activity of the enzyme (PubMed:29550214). It enables E.coli to grow on a nonfermentable carbon source when H(2)O(2) is supplied (PubMed:28696311). Plays a role in the peroxide stress response under anaerobic conditions (PubMed:17464064). However, it does not degrade H(2)O(2) quickly enough to lower the periplasmic H(2)O(2) level below that of the surrounding medium and protect the cell from its toxic effects (PubMed:28696311).<ref>PMID:17464064</ref> <ref>PMID:28696311</ref> <ref>PMID:29550214</ref>
