IUBMB Enzyme Nomenclature


Accepted name: ABC-type D-ribose transporter

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

Other name(s): D-ribose transporting ATPase; D-ribose ABC transporter; rbsACB (gene names)

Systematic name: ATP phosphohydrolase (ABC-type, D-ribose-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 D-ribose.
