They prepared the purees using a commercial polygalacturonase
and a highly purified pectinesterase.

Optimizing grape rootstock production and export of inhibitors of Xylella fastidiosa polygalacturonase
Among the depolymerases, polygalacturonase
is the major enzyme with a hydrolytic function and lyases (or transeleminases) which cleaves glycosidic bonds forming unsaturated product[DELTA](4,5-D-galacturonate) through transelimination reaction .

2000), woolliness results from an imbalance of peptic enzyme activity during the ripening stage, with increased pectinmethylesterase enzyme activity, inhibition of polygalacturonase
activity and an accumulation of peptic substances with low degrees of esterification, which prevent these substances from being soluble.
Moreover, a study on minimally processed papaya showed that softening enzymes like polygalacturonase
are increased within 24 hours as compared to the whole fruit .
The enzymes involved in the breakdown of pectin include pectate lyase, polygalacturonase
Production of polygalacturonase
and increase of longitudinal gas permeability in southern pine by brown-rot and white-rot fungi.
However, the activity of F-5 significantly increased after the endo-[alpha]-D-(1 [right arrow] 4) polygalacturonase

He has also purified a polygalacturonase
inhibitor protein (PGIP) from grapefruit peel.
