IntEnz Enzyme Nomenclature


Accepted name:
ABC-type oligosaccharide transporter
Other name:
oligosaccharide-transporting ATPase
Systematic name:
ATP phosphohydrolase (ABC-type, oligosaccharide-importing)



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. Formerly EC
