BioY protein (IPR003784)

Short name: BioY

Family relationships



BioMNY, a high-affinity biotin transporter, is a member of the ECF (energy-coupling factor) transporters. ECF transporters share a common architecture consisting of pairs of ABC (ATP-binding cassette)-containing ATPases, a conserved transmembrane protein and a transmembrane substrate-capture protein. In the case of the biotin transporter these are represented by BioM, BioN and BioY respectively [PMID: 20738254].

BioY functions as a high-affinity system in the presence of BioMN and as a low-affinity biotin transporter in the absence of BioMN [PMID: 17301237].
