Short name: Cyt_b562

Description

Cytochrome b562 is a haem-containing protein that is expressed in the periplasm of Escherichia coli. In b-type cytochromes, the haem atom is not covalently attached to the polypeptide. Cytochrome b562 has a four-helical bundle structure that is structurally similar to that found in members of the cytochrome c family (IPR002321). Cytochrome b562 has a reduction potential of 167 mV, which sets the energy yield possible in metabolism and is also a key determinant of the rate at which redox reactions proceed [PMID: 11914078].
