EC Number Temperature Stability Minimum [°C] Temperature Stability Maximum [°C] Comment Organism
4.1.1.39 60 65 Rubisco from leaves grown at high temperatures is stable even at 62.5°C. Rubisco from leaves grown at low temperatures decreases its activity above 60°C. The activity of low temperature-Rubisco after the treatment at 65°C is less than that of high temperature-Rubisco by 50%, the Rubisco activation state decreases with increasing temperature above the growth temperature Spinacia oleracea
