IUBMB Enzyme Nomenclature


Accepted name: monosaccharide-transporting ATPase

Reaction: ATP + H2O + monosaccharideout = ADP + phosphate + monosaccharidein

Systematic name: ATP phosphohydrolase (monosaccharide-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. Family of bacterial enzymes importing ribose, xylose, arabinose, galactose and methylgalactoside.
