EC 3.1.1.73

Accepted name: feruloyl esterase

Reaction: feruloyl-polysaccharide + H2O = ferulate + polysaccharide

Glossary entries:
ferulate = 4-hydroxy-3-methoxycinnamate

Other name(s): ferulic acid esterase, hydroxycinnamoyl esterase, hemicellulase accessory enzymes; 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.
