Nuc_H_symport

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)
