   3.1.1.11 | pectin + H2O |
involved in the regulation of the cell wall rigidity, central role in the pollen tube growth and determination of pollen tube morphology |
| 3.1.1.11 | pectin + H2O |
involved in the regulation of the cell wall rigidity, important for the control of hyperhydricity |
| 3.1.1.11 | pectin + H2O |
involved in the regulation of the cell wall rigidity, important role in plant growth and differentiation, enzyme activity in Nausica variety is correlated with ambient temperature |
| 3.1.1.11 | pectin + H2O |
involved in the regulation of the cell wall rigidity, key role in process of fruit ripening |
| 3.1.1.11 | pectin + H2O |
low-temperature blanching of vegetables activates PME, which demethylates cell wall pectins and improves tissue firmness |
| 3.1.1.11 | pectin + H2O |
PME activity gives rise to negatively charged carboxylic groups and protons in the pectic matrix modifying the cell wall charge, apoplasmic pH and potentially the activity of apoplasmic proteins, the enzyme has several physiologic functions in the plant and is involved e.g. in plant growth, xylogenesis, fruit ripening, plant defense, and in general plant-stress signalling, detailed overview, high content of unmethylesterified HGA, generated by high PME activity in cell walls, correlates positively with the susceptibility of plant cultivars to abiotic and biotic stresses, model of PME involvement in plant defences, overview |
| 3.1.1.11 | pectin + H2O |
PME plays an important role in elongation of the pollen tube in pistil, which is essential for delivering sperms into the female gametophyte in sexual plant reproduction, regulation mechanism, overview |
| 3.1.1.11 | pectin + H2O |
ripe var. Easy Pick fruit is characterized by pectin ultradegradation and easy fruit detachment from the calyx, while pectin depolymerization and dissolution in ripe var. Hard Pick fruit is limited, PME activity in vivo is detected only in fruit of the Easy Pick line and is associated with decreased pectin methylesterification, some PME isozymes are apparently inactive in vivo, particularly in green fruit and throughout ripening in the Hard Pick line, limiting polygalacturonase-mediated pectin depolymerization which results in moderately difficult fruit separation from the calyx |
| 3.1.1.11 | pectin + H2O |
the enzyme catalyses the essential first step in bacterial invasion of plant tissues |
| 3.1.1.11 | pectin + H2O |
the enzyme is responsible for the demethylation of galacturonyl residues in high-molecular weight pectin and play s an important role in cell wall metabolism, role of PMEU1 in fruit ripening, overview |
