The polygalacturonase (PG) (EC3.2.1.15) gene family is one of the largest gene families in plants. PG is a pectin-digesting enzyme with a glycoside hydrolase 28 domain.

Polygalacturonase, produced by Botrytis fabae in infected faba bean pods, was separated by isoelectric focusing and tested as possible elicitor of the phytoalexins wyerone acid and wyerone. The ...

Bean polygalacturonase was partially characterized and comparisons were made between the bean enzyme and previously reported higher plant polygalacturonases. Polygalacturonase isolated from bean leaf ...

They also elucidated the molecular mechanism by which the plant polygalacturonase inhibitor protein PGIP specifically binds to pathogenic polygalacturonase PG, hijacking its enzyme activity to ...
