Carbohydrate Research 148 (1986) 71-85
Treatment of cell walls of barley straw with Oxyporus “cellulase” (a mixture of polysaccharide hydrolases) released compounds containing p-coumaroyl and feruloyl groups bound to carbohydrates, two of which were identified as O-[5-O-(trans-p-coumaroyl)-α-l-arabinofuranosyl]-(1→3)-O-β-d-xylopyranosyl-(1→4)-d-xylopyranose (PAXX) and O-[5-O-(trans-feruloyl)-α-l-arabinofuranosyl]-(1→3)-O-β-d-xylopyranosyl-(1→4)-d-xylopyranose (FAXX).

Carbohydrate Research 263 (1994) 257-269
The activity of two forms of ferulic acid esterase (FAE) from Aspergillus niger on a synthetic feruloylated substrate (methyl ferulate) and on 11 different feruloylated oligosaccharides from sugar-beet pulp and wheat bran was determined. The enzymes exhibited different specificities for the various feruloylated substrates and were more active on certain substrates of cell-wall origin than on methyl ferulate. Both enzymes preferred the arabinose residue to which ferulic acid is attached in the furanose form. FAE-I had no clear preference for the type of linkage involved between the ferulic acid units and the oligosaccharide chain. In contrast, FAE-III had a clear requirement for ferulic acid to be attached to O-5 of the Ara f ring while no catalysis was observed when ferulic acid was attached to O-2. Both enzymes showed maximum activity on feruloylated trisaccharides. An increase in the length of the oligosaccharide chain did not preclude catalysis, but feruloylated oligosaccharides of a dp > 3 were hydrolysed at a reduced rate. Our results support the hypothesis that different kinds of ferulic acid esterases exist with different specificities for the oligosaccharide chain of the feruloylated substrates.

Cell wall polysaccharides contain a small amount of ester-linked hydroxycinnamic acid derivatives, such as p-coumaric and ferulic acids. These hydroxycinnamic acids can be coupled oxidatively to form the acid dimers. Dimer formation in the growing plant cell wall would cause the cross-linkage of cell wall polysaccharides and lead to an increase in wall rigidity. Feruloyl polysaccharide esters would also participate with lignin monomers in oxidative coupling pathways to generate a ferulate-polysaccharide-lignin complexes during cell wall development. Feruloyl oligosaccharides derived from feruloyl polysaccharides have been shown to inhibit cell elongation growth induced by auxin or gibberellins. Feruloyl polysaccharides are critical entities in directing wall cross-linking and in limiting biodegradability by microorganisms.

Carbohydrate Research 263 (1994) 227-241
Cell walls from sugar-beet pulp contain some feruloyl groups linked to the pectic neutral side-chains. Enzymic as well as chemical hydrolysis of the pulp yielded a series of feruloylated oligosaccharides, which have been purified by Sephadex LH-20 and Biogel P-2 chromatography in aqueous solvents. Feruloylated arabinose di-, tri-, hexa-, hepta-, and octa-saccharides as well as feruloylated galactose disaccharides were obtained after hydrolysis of the pulp with a mixture of fungal carbohydrases (Driselase). Feruloylated arabinose and galactose monosaccharides were obtained through mild acid hydrolyses. Both arabinose and galactose residues in the side-chains are feruloylated, 50–55% of the feruloyl groups being linked to arabinose residues and 45–50% to galactose residues. It is concluded that 1 out of 56 arabinose residues and 1 out of 16 galactose residues present as pectic side-chains in sugar-beet pulp carry a feruloyl group.

Streptomyces olivochromogenes ferulic acid esterase released free ferulic acid from 0-[5-0-(trans-feruloyl)-α-l-arabinofuranosyl]-(1→3)-O-β-xylopyranosyl-(1→4)-d-xylopyranose (FAXX) prepared from wheat bran. The Km and Vmax of the reaction were 0·24 mm and 0·134 U mg−1, respectively. The enzyme released 0·25% of the covalently bound ferulic acid from sugar beet pectin both in the presence and in the absence of pectinase.

Phytochemistry 44(6) (1997) 1019-1030
Graminaceous cell walls contain arabinoxylans in which some of the Araf residues are 5-O-feruloylated. In the present study, mild acid hydrolysis of (pentosyl-H-3)-labelled Festuca arundinacea cell walls yielded the well-characterized 5-O-Fer-L-Ara (1) and at least seven new (E)-feruloylated oligosaccharides, 2-8. Compound 2 was a feruloylated disaccharide, Fer-(D-Xylp→L-Ara); electrophoresis in molybdate buffer, Smith degradation and methylation analysis showed a (1→2)-linkage. H-1 and C-13 NMR data and susceptibility to commercial β-D-xylosidase indicated a β-linkage. Graded alkaline hydrolysis of 2 showed no evidence for more than one ester group. Hydrolysis with commercial β-xylosidase yielded 5-O-feruloyl-L-arabinose. Compound 2 was thus 2-O-β-D-xylopyranosyl-(5-O-feruloyl)-L-arabinose. We propose that 2 was furanose-linked to a xylan backbone in the intact polymer. Compounds 3-8 also appeared to be O-feruloyl oligosaccharides with a former Araf residue at the reducing terminus. Mild acid hydrolysis of cell walls from twenty other species of grass and one palm also yielded compounds 1-3, and most or all of 4-8. Therefore, these complex feruloylated side-chains of arabinoxylans are widespread or universal in the Gramineae. Their possible biological roles are discussed.

Sequential extractions with alkali have been carried out in order to study the nature of linkages which hold heteroxylans in maize bran cell walls. Treatment with 0.5 m sodium hydroxide at 30 °C for 2 h released all the phenolic acids (p-coumaric, ferulic, and diferulic) but extracted only ~30% of heteroxylans (S1); further treatment with 1.5 m potassium hydroxide at 100 °C for 2 h released the remaining heteroxylans (S2). The heteroxylans from S1 and S2 had a similar neutral sugar composition and structure, but their weight average molecular weights were 270 kDa (Mw/Mn=2) and 370 kDa (Mw/Mn=2.8), respectively. Proteins (5%) are found with polysaccharides from S1 and S2, with different amino acid composition. The results suggest that covalent linkages through phenolic acids are only partly responsible for the associations of maize bran heteroxylans in the cell wall and that linkages to structural cell wall proteins were probably the main cause of heteroxylan insolubility.

Cell wall polysaccharides contain a small amount of ester-linked hydroxycinnamic acid derivatives, such as p-coumaric and ferulic acids. These hydroxycinnamic acids can be coupled oxidatively to form the acid dimers. Dimer formation in the growing plant cell wall would cause the cross-linkage of cell wall polysaccharides and lead to an increase in wall rigidity. Feruloyl polysaccharide esters would also participate with lignin monomers in oxidative coupling pathways to generate a ferulate-polysaccharide-lignin complexes during cell wall development. Feruloyl oligosaccharides derived from feruloyl polysaccharides have been shown to inhibit cell elongation growth induced by auxin or gibberellins. Feruloyl polysaccharides are critical entities in directing wall cross-linking and in limiting biodegradability by microorganisms.
