Enzyme Commission Primary Name: feruloyl esterase

Enzyme Commission Synonyms: ferulic acid esterase, hydroxycinnamoyl esterase, hemicellulase accessory enzymes, FAE-III, cinnamoyl ester hydrolase, FAEA, cinnAE, FAE-I, FAE-II

Standard Gibbs Free Energy (ΔrG in kcal/mol): 74.00185Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
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.
