Beta-glucan-transporting ATPase

From Wikipedia, the free encyclopedia

In enzymology, a beta-glucan-transporting ATPase (EC 3.6.3.42) is an enzyme that catalyzes the chemical reaction

ATP + H₂O + beta-glucan_in $\rightleftharpoons$ ADP + phosphate + beta-glucan_out

The 3 substrates of this enzyme are ATP, H₂O, and beta-glucan, whereas its 3 products are ADP, phosphate, and beta-glucan.

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides acting on acid anhydrides to catalyse transmembrane movement of substances. The systematic name of this enzyme class is ATP phosphohydrolase (beta-glucan-exporting).
