Enzyme Information

3.2.1.15
Endo-polygalacturonase.
based on mapping to UniProt O74213
(1,4-alpha-D-galacturonosyl)(n+m) + H(2)O = (1,4-alpha-D- galacturonosyl)(n) + (1,4-alpha-D-galacturonosyl)(m).
-!- The enzyme catalyzes the random hydrolysis of (1->4)-alpha-D- galactosiduronic linkages in pectate and other galacturonans. -!- Different forms of the enzyme have different tolerances to methyl esterification of the substrate.
