Polygalacturonase

Gene
N/A
Organism
Actinidia deliciosa (Kiwi)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Acts in concert with the pectinesterase, in the ripening process. Is involved in cell wall metabolism, specifically in polyuronide degradation.

Catalytic activityi

Random hydrolysis of (1->4)-alpha-D-galactosiduronic linkages in pectate and other galacturonans.
