Activating Compound | Comment | Organism | Structure |
---|---|---|---|
additional information | a 8 kDa protein (ACT) from the PG1 protein complex is capable of converting the gene product PG2 into a more active and heat-stable form, which increases PG-mediated pectin degradation in vitro and stimulates PG-mediated tissue breakdown in planta. Addition of the 8 kDa protein to tomato PG2 causes a 4fold to 5fold increase in activity | Solanum lycopersicum | |
additional information | apple or peach lipid transfer proteins significantly increase PG activity (more than 2fold) and heat stability | Aspergillus niger |
