Accepted name: ABC-type D-xylose/L-arabinose transporter
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, ABC-type D-xylose transporter and EC, ABC-type L-arabinose transporter).
