BRITE hierarchy
Sysname
ATP phosphohydrolase (maltose-importing)
Reaction(IUBMB)
ATP + H2O + maltoseout = ADP + phosphate + maltosein [RN:R00086]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
H2O [CPD:C00001];
maltose [CPD:C00208]
Product
ADP [CPD:C00008];
phosphate [CPD:C00009];
maltose [CPD:C00208]
Comment
ABC-type (ATP-binding cassette-type) ATPase, characterized 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.
