the enzyme is involved in the degradation of condensed tannins, complex tannins, gallotannins, and ellagitannins produced by different plant species in almost all tissue types, e.g. bark, wood, leaf, fruit, root and seed, overview, tannin structure and physiologic effects, degradation mechanism, and pathways, detailed overview

tannases hydrolyze only those substrates that contain at least two phenolic OH groups in the acid component. The esterified COOH group must be on the oxidized benzene ring and must not be ortho to one of the OH groups. Benzoic esters (methyl benzoate, and ethyl benzoate), hydroxybenzoic esters (methyl 4-hydroxybenzoate, ethyl 4-hydroxybenzoate, propyl 4-hydroxybenzoate, and butyl 4-hydroxybenzoate), vanillic ester (methyl vanillate), gentisic ester (methyl gentisate), salicylic ester (methyl salicylate), ferulic esters (ferulic methyl ester and ferulic ethyl ester), ellagic, chlorogenic acids, quercetin, catechin, epicatechin, gallocatechin, epigallocatechin or 4-nitrophenyl beta-D-glucopyranoside are not metabolized

tannase cleaves ester bonds between gallic acid and glucose in tannic acid and m-digallic acid ester linkages, named depside bonds, it also hydrolyzes (+)-epicatechin gallate and (+)-epigallocatechin-3-gallate
