IUBMB Enzyme Nomenclature


Accepted name: ABC-type D-allose transporter

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

Other name(s): D-allose transporting ATPase; D-allose ABC transporter; alsBAC (gene names)

Systematic name: ATP phosphohydrolase (ABC-type, D-allose-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. The enzyme from the bacterium Escherichia coli interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of D-allose, which can be used by the bacterium as a sole carbon source.
