Pectinesterase - Wikipedia
网页Pectinesterase (EC 3.1.1.11; systematic name pectin pectylhydrolase) is a ubiquitous cell-wall-associated enzyme that presents several isoforms that facilitate plant cell wall modification and subsequent breakdown. It catalyzes the following reaction: pectin + n H 2 O = n methanol + pectate.
Pectinesterase - an overview | ScienceDirect Topics
网页Pectin methylesterase (EC.3.1.1.11) also called pectinesterase (systematic name: pectin pectyl hydrolase) cleaves methanol from esterified carboxyl groups to yield low-methoxyl pectin and polygalacturonic acid. High-methoxyl pectin is the preferred substrate.
Plant pectin acetylesterase structure and function: new insights …
网页2017年6月8日 · Pectins are plant cell wall polysaccharides that can be acetylated on C2 and/or C3 of galacturonic acid residues. The degree of acetylation of pectin can be modulated by pectin acetylesterase (EC 3.1.1.6, PAE).
Pectinesterase - an overview | ScienceDirect Topics
网页Pectinesterase is an enzyme involved in the degradation of pectin by hydrolyzing the carboxyl ester bond of galacturonic acid, thereby reducing viscosity in fruit juices and aiding in the clarification process.
Pectinesterase - an overview | ScienceDirect Topics
网页Pectinesterase (PE/PME, EC 3.1.1.11) is a kind of pectinase used to catalyze the removement of methoxyl group from HG, which is also known as pectin demethoxylase, pectin methoxylase or pectin methylesterase.

网页2013年10月19日 · Pectinesterase catalyzes the de-esterification of these polymers before abscission, as has been observed in poinsettia (Lee et al. 2008), making pectin accessible to other hydrolytic enzymes, including PGs, for further breakdown.
Pectinolytic enzymes-solid state fermentation, assay methods …
网页2018年3月24日 · Pectinolytic enzymes are a group of related enzymes that hydrolyse pectic substances. Pectin is a complex polysaccharide present in the middle lamella of plant cell walls. It is composed of multiple units of D-Galacturonic acid linked by α (1, 4) glycosidic linkage.
Genome-wide identification, phylogeny and expression analysis …
网页2019年12月27日 · Pectins, the major components of cell walls in plants, are synthesized and secreted to cell walls as highly methyl-esterified polymers and then demethyl-esterified by pectin methylesterases (PMEs)....
Frontiers | Pectin Methylesterases: Cell Wall Remodeling Proteins …
网页Pectin methylesterases (PMEs) are present in multigene families and encode isoforms with different action patterns by removal of methyl esters to influencing the properties of cell wall.
Recent Advances in Understanding the Roles of Pectin as an …
网页2021年8月19日 · The structural diversity of pectins, along with the numerous combinations of the enzymes responsible for pectin biosynthesis and modification, plays key roles in ensuring the specificity and plasticity of cell wall remodeling in different cell types and under different environmental conditions.
