Phenolic profiling of caffeic acid O-methyltransferase-deficient poplar reveals novel benzodioxane oligolignols [PDF]

, 2004
Caffeic acid O-methyltransferase (COMT) catalyzes preferentially the methylation of 5-hydroxyconiferaldehyde to sinapaldehyde in monolignol biosynthesis. Here, we have compared HPLC profiles of the methanol-soluble phenolics fraction of xylem tissue from

Silencing CHALCONE SYNTHASE in maize impedes the incorporation of tricin into lignin and increases lignin content [PDF]

, 2016
Lignin is a phenolic heteropolymer that is deposited in secondary-thickened cell walls, where it provides mechanical strength. A recent structural characterization of cell walls from monocot species showed that the flavone tricin is part of the native ...

Characterization of human S-adenosyl-homocysteine hydrolase in vitro and identification of its potential inhibitors

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017
Human S-adenosyl-homocysteine hydrolase (SAHH, E.C.3.3.1.1) has been considered to be an attractive target for the design of medicines to treat human disease, because of its important role in regulating biological methylation reactions to catalyse the ...

Mass spectrometry-based fragmentation as an identification tool in lignomics [PDF]

, 2010
The ensemble of all phenolics for which the biosynthesis is coregulated with lignin biosynthesis, i.e., metabolites from the general phenylpropanoid, monolignol, and (neo)-lignan biosynthetic pathways and their derivatives, as well as the lignin ...

Origins of Noncovalent Interactions in Lignocellulosic Biomass and Potential Implications on Recalcitrance. [PDF]

Chemphyschem
Quantum mechanical calculations on 189 lignin‐hemicellulose models reveal that noncovalent interactions are modulated by methoxy substitution on lignin and carboxylate groups in monosaccharides. Increased methoxy substitution and carboxylation significantly strengthens their binding.

Coniferyl alcohol reactivity at the air/water interface

Comptes Rendus. Biologies, 2004
In order to investigate the sensitivity of the lignin monomer coupling reactions to the environment physicochemical conditions, coniferyl alcohol (CA) was polymerised at the air/water interface. Characterisation of the interface during the reaction by surface pressure measurement and ellipsometry demonstrates that the reaction occurs near or at the ...
