Metal transport protein CbiM/NikMN (IPR002751)

Short name: CbiM/NikMN

Overlapping homologous superfamilies


Family relationships


This entry represents the integral membrane protein CbiM, which forms part of the energy-coupling factor (ECF) transporter complex CbiMNOQ that is involved in cobalt import [PMID: 16352848, PMID: 20868747], and plays a role in the cobalamin synthesis pathway. CbiM is the substrate-specific component of the complex and is a seven-transmembrane protein [PMID: 16352848]. This entry also includes related proteins, such as NikMN, which may be involved in nickel transport [PMID: 16352848]. The CbiMNQO and NikMNQO systems form part of the coenzyme B12 biosynthesis pathway [PMID: 18174128].
