Family

Purine ribonucleoside efflux pump, NepI (IPR023680)

Short name: MFS_NepI

Family relationships

Description

Among the different families of transporter, only two occur ubiquitously in all classifications of organisms. These are the ATP-Binding Cassette (ABC) superfamily and the Major Facilitator Superfamily (MFS). The MFS transporters are single-polypeptide secondary carriers capable only of transporting small solutes in response to chemiosmotic ion gradients [PMID: 9529885, PMID: 9868370].

This entry represents the nucleoside efflux permease-inosine (NepI) subfamily of the MSF superfamily. These proteins are nucleoside efflux pumps and are involved in the efflux of purine ribonucleosides, such as guanosine, adenosine and especially inosine [PMID: 16040204, PMID: 20814730].
