General annotation (Comments)

Function

Has pectate lyase activity By similarity.

Catalytic activity

Eliminative cleavage of (1->4)-alpha-D-galacturonan to give oligosaccharides with 4-deoxy-alpha-D-galact-4-enuronosyl groups at their non-reducing ends.

Cofactor

Binds 1 calcium ion By similarity.

Pathway

Glycan metabolism; pectin degradation; 2-dehydro-3-deoxy-D-gluconate from pectin: step 2/5.

Subunit structure

Monomer.

Tissue specificity

Pollen and flowers.

Post-translational modification

The N-terminus is blocked.

Allergenic properties

Causes an allergic reaction in human. This is one of the major allergens of the ragweed pollen. Ref.1
