Reaction: feruloyl-polysaccharide + H2O = ferulate + polysaccharide
ferulate = 4-hydroxy-3-methoxycinnamate
Other name(s): ferulic acid esterase; hydroxycinnamoyl esterase; hemicellulase accessory enzyme; FAE-III; cinnamoyl ester hydrolase; FAEA; cinnAE; FAE-I; FAE-II
Sytematic name: 4-hydroxy-3-methoxycinnamoyl-sugar hydrolase
Comments: Catalyses the hydrolysis of the 4-hydroxy-3-methoxycinnamoyl (feruloyl) group from an esterified sugar, which is usually arabinose in "natural" substrates. p-Nitrophenol acetate and methyl ferulate are poorer substrates. All microbial ferulate esterases are secreted into the culture medium. They are sometimes called hemicellulase accessory enzymes, since they help xylanases and pectinases to break down plant cell wall hemicellulose.
