Plant cell wall lignification and monolignol metabolism [PDF]
Frontiers in Plant Science, 2013 Plants are built of various specialized cell types that differ in their cell wall composition and structure. The cell walls of certain tissues (xylem, sclerenchyma) are characterized by the presence of the heterogenous polymer lignin that plays an ...

Structural analysis of rice Os4BGlu18 monolignol β-glucosidase.
PLoS ONE, 2021 Monolignol glucosides are storage forms of monolignols, which are polymerized to lignin to strengthen plant cell walls. The conversion of monolignol glucosides to monolignols is catalyzed by monolignol β-glucosidases.

Reductive Cleavage Method for Quantitation of Monolignols and Low‐Abundance Monolignol Conjugates [PDF]
ChemSusChem, 2018 AbstractInvited for this month's cover is the group of Prof. John Ralph at the University of Wisconsin–Madison. The image shows the fragmentation of various lignins into monomeric components using the derivatization followed by reductive cleavage (DFRC) method, with the included mechanism providing the details for the derivatization of these lignins ...

Enzyme-Enzyme Interactions in Monolignol Biosynthesis [PDF]
Frontiers in Plant Science, 2019 The enzymes that comprise the monolignol biosynthetic pathway have been studied intensively for more than half a century. A major interest has been the role of pathway in the biosynthesis of lignin and the role of lignin in the formation of wood. The pathway has been typically conceived as linear steps that convert phenylalanine into three major ...

Identification and characterization of a set of monocot BAHD monolignol transferases [PDF]
Plant Physiology, 2022 Abstract Plant BAHD acyltransferases perform a wide range of enzymatic tasks in primary and secondary metabolism. Acyl-CoA monolignol transferases, which couple a CoA substrate to a monolignol creating an ester linkage, represent a more recent class of such acyltransferases.

Plant Cell Biology: The ABC of Monolignol Transport [PDF]
Current Biology, 2012 Lignins are complex aromatic heteropolymers that reinforce the cell walls of terrestrial plants. A new study identifies an ATP-binding cassette ABC transporter that pumps a monolignol lignin precursor across the plasma membrane.

AtABCG29 Is a Monolignol Transporter Involved in Lignin Biosynthesis [PDF]
Current Biology, 2012 Lignin is the defining constituent of wood and the second most abundant natural polymer on earth. Lignin is produced by the oxidative coupling of three monolignols: p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol. Monolignols are synthesized via the phenylpropanoid pathway and eventually polymerized in the cell wall by peroxidases and ...

5-Hydroxyconiferyl Aldehyde Modulates Enzymatic Methylation for Syringyl Monolignol Formation, a New View of Monolignol Biosynthesis in Angiosperms [PDF]
Journal of Biological Chemistry, 2000 S-Adenosyl-L-methionine-dependent caffeate O-methyltransferase (COMT, EC 2.1.1.6) has traditionally been thought to catalyze the methylation of caffeate and 5- hydroxyferulate for the biosynthesis of syringyl monolignol, a lignin constituent of angiosperm wood that enables efficient lignin degradation for cellulose production.

Understanding Lignification: Challenges Beyond Monolignol Biosynthesis [PDF]
Plant Physiology, 2010 Lignin, a major component of vascular plant cell wall, provides mechanical support for plants to stand upright and enables xylems to withstand the negative pressure generated during water transport.

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 ...
