Activating Compound

EC Number Activating Compound Comment Organism Structure
2.4.1.173 ATP slightly stimulation at low concentration Pisum sativum
2.4.1.173 phosphatidylcholine 33% increase of activity Pisum sativum
2.4.1.173 phosphatidylethanolamine increases 125% of activity Pisum sativum
2.4.1.173 phosphatidylserine 33% increase of activity Pisum sativum
2.4.1.173 phospholipase treatment with phospholipases A, C and D lowers activity 21-29%, the effect of phospholipase A is completely reverse by phosphatidylethanolamine but not by phosphatidylcholine or phosphatidylserine, after phospholipase C or D treatment each phospholipid brings about a partial recovery of activity but phosphatidylethanolamine is superior Pisum sativum
