ENZYME entry: EC 3.1.1.73

Accepted Name
Feruloyl esterase.
Alternative Name(s)
Cinnamoyl ester hydrolase.
Ferulic acid esterase.
Hydroxycinnamoyl esterase.
Reaction catalysed
Feruloyl-polysaccharide + H(2)O <=> ferulate + polysaccharide
Comment(s)
  • 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.
