Phenylephrine, a small molecule, inhibits pectin methylesterases
Biochemical and Biophysical Research Communications, 2019Pectin methylesterases (PMEs) catalyze pectin demethylation and facilitate the determination of the degree of methyl esterification of cell wall in higher plants. The regulation of PME activity through endogenous proteinaceous PME inhibitors (PMEIs) alters the status of pectin methylation and influences plant growth and development.

Influence of calcium on pectin methylesterase behaviour in the presence of medium methylated pectins
Carbohydrate Polymers, 2011Pectins account for one of the major polysaccharides of plant cell walls and are commonly used in the food industry as gelling and stabilising agents. Pectin methylesterase (PME) can alter pectin structure and affect their gelling properties by de-esterifying galacturonic acid.

Pectin methylesterase (PME) catalyses the de-methylesterification of pectin in plant cell walls during cell elongation. While it is generally assumed that fungal PMEs have a random mode of action, plant PMEs are thought to act in a processive manner to generate long stretches of non-methylesterified residues. However, it is unlikely that all plant PMEs

Gelation of high methoxy pectin in the presence of pectin methylesterases and calcium
Carbohydrate Polymers, 2009Abstract High methoxy pectin was submitted to various amounts of a fungal pectin methylesterase (PME) from Aspergillus aculeatus and of a plant PME from orange in the presence of calcium. The systems were characterized by rheological means during the gelation process.

Structure-Function of a Proteinaceous Inhibitor of Plant Pectin Methylesterase
2003A protein acting as a powerful inhibitor of plant pectin methylesterase has been isolated from kiwi fruit. The protein was purified by affinity chromatography on Sepharose-bound tomato pectin methylesterase. The purified protein has a molecular mass close to 16 kDa, as estimated by SDS-PAGE, whereas its molecular mass appears to be 25 kDa by gel ...

Behavior of pectin methylesterases in pectic gels
2009Pectic gel has been used as a simplified solid matrix to study the behaviour of two pectin methylesterases (PMEs) - one from Aspergillus aculeatus and one from orange. Gel was obtained during demethoxylation of a high methoxy lime pectin with a initial degree of methylation of 71 by PME action in the presence of calcium ions.
