 Nitrosomonas europaea
1.7.2.6 additional information each monomer contains 7 c-type hemes and a novel heme known as P460, the role of the c-hemes appears to be the transfer of electrons from the P460 active site to 1 or more electron acceptors, cytochrome c554 is the most likely candidate as the electron acceptor Nitrosomonas europaea
