Reaction: ATP + H2O + D-xylose-[xylose-binding protein][side 1] = ADP + phosphate + D-xylose[side 2] + [xylose-binding protein][side 1]
Other name(s): D-xylose transporting ATPase; D-xylose ABC transporter; xylFGH (gene names)
Systematic name: ATP phosphohydrolase (ABC-type, D-xylose-transporting)
Comments: ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of D-xylose.
