tyrosine phosphorylation and proteolysis are distinct events as both phosphorylated and nonphosphorylated lipocortins could be cleaved by the membrane protease , but prephosphorylation enhanced the rate of proteolysis 2-fold during the initial reaction and by 60 min almost half of the phosphorylated lipocortin was proteolyzed .
