IUBMB Enzyme Nomenclature


Accepted name: ABC-type L-arabinose transporter

Reaction: ATP + H2O + L-arabinose-[arabinose-binding protein][side 1] = ADP + phosphate + L-arabinose[side 2] + [arabinose-binding protein][side 1]

Other name(s): L-arabinose transporting ATPase; L-arabinose ABC transporter; araFGH (gene names)

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

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 L-arabinose.
