Activating Compound

Activating Compound	Comment	Organism	Structure
additional information	although SPS activity does not display an endogenous rhythm of activity in continuous light, activation of SPS at the end of the dark period is observed. This activation is possibly controlled by covalent modification, because it is inhibited by okadaic acid while the SPS protein level does not significantly change. The highest SPS activity is observed after 21 days of cold acclimation under long day conditions. This increased activity is not related to an increase in SPS gene expression or protein content	Deschampsia antarctica
