1 mM, 119% of initial activity
stimulation
-
enhances activity of microsomal enzyme
-
when the concentration of calcium is increased, calmodulin is released from UBE3B, resulting in an increase in ubiquitylation activity
when the concentration of calcium is increased, calmodulin is released from UBE3B, resulting in an increase in ubiquitylation activity
-
only for sucrose synthesis
