| Addtional Information | FUNCTION:Acts in the modification of cell walls via demethylesterification of cell wall pectin. Plays an important role in growth of pollen tubes in female floral tissues, possibly via enhancing the interaction between the pollen tube and female floral tissues by modification of the cell walls.CATALYTIC ACTIVITY:Pectin n H(2)O = n methanol pectate.Note=Distributed in the whole pollen tube, including the plasma membrane and pollen tube wall.TISSUE SPECIFICITY:Expressed specifically in pollen grains and pollen tubes.SIMILARITY:Belongs to the pectinesterase family. |
