Enzyme Information

3.1.1.73
Feruloyl esterase.
based on mapping to UniProt O42807
Feruloyl-polysaccharide + H(2)O = ferulate + polysaccharide.
-!- Catalyzes 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.
