General annotation (Comments)

Function

Probably involved in the degradation of methylated oligogalacturonides present in the periplasm.

Catalytic activity

Pectin + n H2O = n methanol + pectate.

Pathway

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

Subcellular location

Cell outer membrane; Lipid-anchor.

Induction

By pectin.

Sequence similarities

Belongs to the pectinesterase family.
