D-xylose-proton symporter
Alternative name(s):
D-xylose transporter
Gene names
Name:xylE
Ordered Locus Names:b4031, JW3991
OrganismEscherichia coli (strain K12)
Taxonomic identifier83333 [NCBI]
Taxonomic lineageBacteriaProteobacteriaGammaproteobacteriaEnterobacterialesEnterobacteriaceaeEscherichia

Protein attributes

Sequence length491 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Uptake of D-xylose across the boundary membrane with the concomitant transport of protons into the cell (symport system).

Subcellular location

Cell inner membrane; Multi-pass membrane protein.

Induction

By xylose.

Miscellaneous

E.coli has two D-xylose transport systems that accumulate sugar against a concentration gradient: the xylE system which utilizes the electrochemical gradient of protons and that is insensitive to cold osmotic shock and the xylF system that uses a high-energy phosphate compound and is sensitive to cold osmotic shock.

Sequence similarities

Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family. [View classification]
