ENZYME entry: EC 3.2.1.15

Accepted Name
endo-polygalacturonase.
Alternative Name(s)
pectinase.
pectin depolymerase.
polygalacturonase.
Reaction catalysed
(1,4-alpha-D-galacturonosyl)n+m + H2O <=> (1,4-alpha-D-galacturonosyl)n + (1,4-alpha-D-galacturonosyl)m
Comment(s)
  • 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.
