Feruloyl esterase
نویسنده
چکیده
Feruloyl esterase forms a part of the enzyme complex that acts collectively and synergistically to completely hydrolyze xylan to its monomers. The enzyme has found potential uses in a wide variety of applications of interest to the agrifood and pharmaceutical industries. This review describes the enzymology of feruloyl esterases involved in xylan degradation. The occurrence of feruloyl esterases in various microorganisms and their physiochemical properties are presented. The nature of the enzyme substrates and products, the role of synergistic interactions with xylanases and other accessory enzymes, as well as the sequence-structure relating to the reaction mechanism are emphasized. Index Entries: Feruloyl esterase; ferulic acid and crosslinks; feruloylated oligosaccharide; hydroxycinnamic acid; glucurono arabinoxylan.

Product patterns of a feruloyl esterase from Aspergillus nidulans on large feruloyl-arabino-xylo-oligosaccharides from wheat bran.
A purified feruloyl esterase (EC 3.1.1.73) from Aspergillus nidulans produced in Pichia pastoris was used to study the de-esterification of large feruloyl oligosaccharides consisting of 4 to 20 pentose residues and (xylose plus arabinose) and one ferulic acid residue. The feruloyl oligosaccharides were prepared from total oligosaccharidic hydrolysates from wheat bran treated with a purified end...
متن کاملScreening and identification of a feruloyl esterase producing bacteria Burkholderia fungorum A216
A bacterial strain named A216, with feruloyl esterase producing capability, was isolated from forest soil after enrichment. The strain was identified at the species level by morphology, physiological-biochemical tests and 16S rRNA gene sequencing assay. The results revealed that strain A216 was accurately identified as Burkholderia fungorum, and the ITS sequence of the species was submitted to ...
متن کاملCharacterization of a feruloyl esterase from Lactobacillus plantarum.
Lactobacillus plantarum is frequently found in the fermentation of plant-derived food products, where hydroxycinnamoyl esters are abundant. L. plantarum WCFS1 cultures were unable to hydrolyze hydroxycinnamoyl esters; however, cell extracts from the strain partially hydrolyze methyl ferulate and methyl p-coumarate. In order to discover whether the protein Lp_0796 is the enzyme responsible for t...
متن کاملMolecular determinants of substrate specificity in the feruloyl esterase module of xylanase 10B from Clostridium thermocellum.
Feruloyl esterases play a key role in the degradation of the intricate structure of the plant cell wall by hydrolysing the ferulate ester groups involved in the cross-linking between hemicelluloses and between hemicellulose and lignin. The structure of the feruloyl esterase module of Clostridium thermocellum cellulosomal xylanase 10B has been reported previously. It displays the alpha/beta hydr...
متن کاملRegulation of the feruloyl esterase (faeA) gene from Aspergillus niger.
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) from Aspergillus niger depends on D-xylose (expression is mediated by XlnR, the xylanolytic transcriptional activator) and on a second system that re...
