Abstract:
Ferulic acid (3-methoxy-4-hydroxycinnamic acid), present in complex plant cell walls, is covalently cross-linked to polysaccharides by ester bonds and to components of lignin mainly by ether bonds. Ferulic acid has also been shown to occur in dimer- and trimerized forms through oxidative coupling between esterified and/or etherified ferulic acid residues. These cross-links are among the factors most inhibitory to digestion of complex plant cell walls in ruminants. Recently obtained information on ferulic acid and ferulic acid esterases in relation to complex plant cell wall biodegradation is r

Abstract:
ABSTRACT Feruloyl esterases can remove aromatic residues (e.g., ferulic acid) from plant cell wall polysaccharides (xylan, pectin) and are essential for complete degradation of these polysaccharides. Expression of the feruloyl esterase-encoding gene (faeA) fromAspergillus niger depends on d-xylose (expression is mediated by XlnR, the xylanolytic transcriptional activator) and on a second system that responds to aromatic compounds with a defined ring structure, such as ferulic acid and vanillic acid. Several compounds were tested, and all of the inducing compounds contained a benzene ring which

Abstract:
Feruloyl esterases, a subclass of the carboxylic acid esterases (EC 3.1.1.1), are able to hydrolyse the ester bond between the hydroxycinnamic acids and sugars present in the plant cell wall. The enzymes have been classified as type A or type B, based on their substrate specificity for aromatic moieties. We show that Neurospora crassa has the ability to produce multiple ferulic acid esterase activities depending upon the length of fermentation with either sugar beet pulp or wheat bran substrates. A gene identified on the basis of its expression on sugar beet pulp has been cloned and overexpres

ABSTRACT The cellulosome of Clostridium thermocellum is a multiprotein complex with endo- and exocellulase, xylanase, β-glucanase, and acetyl xylan esterase activities. XynY and XynZ, components of the cellulosome, are composed of several domains including xylanase domains and domains of unknown function (UDs). Database searches revealed that the C- and N-terminal UDs of XynY and XynZ, respectively, have sequence homology with the sequence of a feruloyl esterase of strain PC-2 of the anaerobic fungusOrpinomyces.

Homology modeling showed that the FAE contained the catalytic triad composed of Ser80-His236-Asp177, and a classical Gly-X-Ser-X-Gly nucleophile motif commonly found in esterases. Under optimum pH and temperature (pH 7.0, 40 °C), 1 nmole FAE catalyzed the release of 19.75 ± 0.24 µg ferulic acid (FA) from 100 mg corn fiber (CF) in 1 h, which re
