Expression

Organism Comment Expression
Glycine max the enzyme is activated in response to heat shock. Pectin methylesterae activity during the 40°C treatment (2 h) is higher, by about 2.2fold, than that with the 28°C control treatment up

General Information

General Information Comment Organism
physiological function the recovery of heat shock protein-released Ca2+ in Ca2+-pectate reconstitution through pectin methylesterase activity is required for cell wall remodelling during heat shock protein in soybean which, in turn, retains plasma membrane integrity and co-ordinates with heat shock proteins to confer thermotolerance Glycine max
