General Information
| General Information | Comment | Organism |
|---|---|---|
| physiological function | the enzyme is involved in the metabolism (i.e., remodelling) of the cell-wall pectin and, hence, takes part in important physiological processes associated with both vegetative and reproductive plant development, including cell wall extension and stiffening, cellular adhesion and separation, fruit ripening, wood development, stem elongation, leaf growth, microsporogenesis, seed germination, and pollen tube growth. In addition, the enzyme is associated with plant defence responses upon biotic (including insect herbivory) or abiotic (e.g., cold, wounding) stresses. Pectin methylesterase is a ribosome-inactivating protein, inhibiting the translation process | Solanum lycopersicum |
