EC 3.6.3.42

Accepted name: β-glucan-transporting ATPase

Reaction: ATP + H2O + β-glucanin = ADP + phosphate + β-glucanout

Systematic name: ATP phosphohydrolase (β-glucan-exporting)

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. An enzyme found in Gram-negative bacteria that exports β-glucan.
