EC 7.5.2.2     
Accepted name: ABC-type oligosaccharide transporter
Reaction: ATP + H2O + oligosaccharide-[oligosaccharide-binding protein][side 1] = ADP + phosphate + oligosaccharide[side 2] + [oligosaccharide-binding protein][side 1]
Other name(s): oligosaccharide-transporting ATPase
Systematic name: ATP phosphohydrolase (ABC-type, oligosaccharide-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 lactose, melibiose and raffinose.
