EC 7.5.2.1     
Accepted name: ABC-type maltose transporter
Reaction: ATP + H2O + maltose-[maltose-binding protein][side 1] = ADP + phosphate + maltose[side 2] + [maltose-binding protein][side 1]
Other name(s): maltose ABC transporter; maltose-transporting ATPase
Systematic name: ATP phosphohydrolase (ABC-type, maltose-importing)
Comments: An 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, found in bacteria, interacts with an extracytoplasmic substrate binding protein and mediates the import of maltose and maltose oligosaccharides.
