EC 7.5.2.13

Reaction: (1) ATP + H₂O + D-xylose-[xylose-binding protein]_{[side 1]} = ADP + phosphate + D-xylose_{[side 2]} + [xylose-binding protein]_{[side 1]}
(2) ATP + H₂O + L-arabinose-[arabinose-binding protein]_{[side 1]} = ADP + phosphate + L-arabinose_{[side 2]} + [arabinose-binding protein]_{[side 1]}

Systematic name: ATP phosphohydrolase (ABC-type, D-xylose/L-arabinose-importing)

Comments: ATP-binding cassette (ABC) type transporter with a 10-transmembrane-spanning (TMD) subunit and a single nucleotide binding domain. The enzyme from the archaeon Sulfolobus acidocaldarius interacts with an extracytoplasmic sugar-binding protein and mediates the uptake of of D-xylose and L-arabinose (cf. EC 7.5.2.10, ABC-type D-xylose transporter and EC 7.5.2.12, ABC-type L-arabinose transporter).
