IUBMB Enzyme Nomenclature

EC 3.6.3.19

Accepted name: maltose-transporting ATPase

Reaction: ATP + H2O + maltoseout = ADP + phosphate + maltosein

Systematic name: ATP phosphohydrolase (maltose-importing)

Comments: ABC-type (ATP-binding cassette-type) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. Comprises bacterial enzymes that import maltose and maltose oligosaccharides.
