C6- and C1-substituted. De-esterification proceeds via a specific pattern, depending on the degree of polymerization. Initially, a first methyl ester of the oligomer is hydrolysed, resulting in one free carboxyl group. Subsequently this first product is preferred as a substrate and is de-esterified for a second time. This product is then accumulated and hereafter de-esterified further to the final product. The saturated hexamer is an exception to this: three methyl esters are removed very rapidly instead of two methyl esters.

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

gelling properties of commercial pectins after PME treatment are characterized. The final degree of esterification of the high- and low-methoxy pectins reaches 6% after the PME treatment, while deesterification of low-methoxy amidated pectin stops at 18%. Deesterification of high-methoxy pectin is tailored to be 40%, which is equivalent to the deesterification of commercial low-methoxy pectin. The pectin gel with relatively high peak molecular weight and low deesterification, which is produced from high-methoxy pectin, exhibits the greatest hardness, gumminess, chewiness, and resilience. The hardness of low-methoxy amidated pectin increases over 300% after PME deesterification

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

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
