General annotation (Comments)

Function

Acts in the modification of cell walls via demethylesterification of cell wall pectin By similarity.

Catalytic activity

Pectin + n H2O = n methanol + pectate.

Pathway

Glycan metabolism; pectin degradation; 2-dehydro-3-deoxy-D-gluconate from pectin: step 1/5.

Sequence similarities

Belongs to the pectinesterase family.

Sequence caution

The sequence AAF69174.1 differs from that shown. Reason: Erroneous gene model prediction.
