Family Report for: Tannase


Family Tannase
Block X
Tannase and feruloyl esterase. This family includes fungal tannase and feruloyl esterase type C (FAE-C).Tannases hydrolyze the galloyl ester bond in tannins to release gallic acid. It also includes several bacterial homologues of unknown function. aspor-q2uh24 is neither a feruloyl esterase nor a tannase but a paraben hydrolase (Koseki et al.). MHETase from Ideonella sakaiensis idesa-mheth does not show activity on pNP-aliphatic esters or typical aromatic ester compounds catalyzed by the tannase family enzymes, such as ethyl gallate and ethyl ferulate. However some mutants of idesa-mheth can hydrolyze BHET ( Palm et al.). It is an exo-PETase. Another family of bacterial tannases has been described: Tannase_Bact. Two enzymes in Ideonella sakaiensis (for example) act on PET (Poly ethylene terephthalate): idesa-peth from Polyesterase-lipase-cutinase family and idesa-mheth which acts on extremity of PET (Exo-PETase Function) and on MHET the product of hydrolysis of PET. MHETase belongs to the Tannase family Feruloyl esterases are distributed in different sub-classes type-A B C,D and E and fall respectively in the following families. Type-A in Lipase_3, Type-B in Esterase_phb (PHB depolymerase), Type-C in Tannase, Type-D in FaeC, Type-E in A85-Feruloyl-Esterase, Type-F in BD-FAE
