Function
function
May function in depolymerizing pectin during pollen development, germination, and tube growth. Acts as an exo-polygalacturonase.
Catalytic activity
- [(1->4)-alpha-D-galacturonosyl](n) + H2O = [(1->4)-alpha-D-galacturonosyl](n-1) + alpha-D-galacturonate
[(1→4)-α-D-galacturonosyl](n) RHEA-COMP:14570 + CHEBI:15377 = [(1→4)-α-D-galacturonosyl](n-1) RHEA-COMP:14572 + CHEBI:58658
