The enzyme tannase (EC 3.1.1.20) catalyzes the following reaction: digallate + H2O = 2 gallate
It is a key enzyme in the degradation of gallotannins and ellagicitannins, two types of hydrolysable tannins. Specifically, tannase catalyzes the hydrolysis of ester and depside bonds of hydrolysable tannins to release glucose and gallic or ellagic acid.
