Capsular-polysaccharide-transporting ATPase explained

In enzymology, a capsular-polysaccharide-transporting ATPase is an enzyme that catalyzes the chemical reaction

ATP + H₂O + capsular polysaccharidein

\rightleftharpoons ADP + phosphate + capsular polysaccharideout

The 3 substrates of this enzyme are ATP, H₂O, and capsular polysaccharide, whereas its 3 products are ADP, phosphate, and capsular polysaccharide.

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