Nuc_H_symport

• PFAM accession number: PF03825
• Interpro abstract (IPR004740):

  This family of proteins transports nucleosides at a high affinity. The transport mechanism is driven by proton motive force. This family includes nucleoside permease (NupG) and xanthosine permease (XapB) from Escherichia coli.

• GO process: nucleoside transport (GO:0015858)
• GO component: integral component of membrane (GO:0016021)
• GO function: nucleoside transmembrane transporter activity (GO:0005337)
