Reaction: ATP + H2O + β-glucan[side 1] = ADP + phosphate + β-glucan[side 2]
Other name(s): β-glucan-transporting ATPase
Systematic name: ATP phosphohydrolase (ABC-type, β-glucan-exporting)
Comments: An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. An enzyme found in Gram-negative bacteria that exports β-glucans.
