activation
-
stimulates
-
poly-lysine has a substrate-specific inhibitory effect on the CKII alpha subunit, whereas it stimulates the activity of the CKII holoenzyme
-
strong, only with phosphorylase kinase as substrate, i.e. autophosphorylation, inhibits activity of activated and nonactivated enzyme with other substrates
-
1.5 to 3fold
-
stimulates 2fold at 1.5 mg/ml
-
activation
-
stimulates 1.5-3fold at 0.0036 mg/ml
-
activates hydrolysis of cell walls of Micrococcus luteus, no influence of hydrolysis of soluble peptidoglycan
-
activation
-
100 mg/l, 2fold activity enhancement
-
activation may be related to transition from 10 S to 6 S form of myosin ATPase conformation
-
strong activation of Nitrosomonas europaea cytochrome c oxidation
