Sysname
ATP phosphohydrolase (beta-glucan-exporting)
Reaction(IUBMB)
ATP + H2O + beta-glucanin = ADP + phosphate + beta-glucanout [RN:R00086]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
H2O [CPD:C00001];
beta-glucan [CPD:C00551]
Product
ADP [CPD:C00008];
phosphate [CPD:C00009];
beta-glucan [CPD:C00551]
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. An enzyme found in Gram-negative bacteria that exports beta-glucan.
