tokens: The inhibition by the RIalpha subunit is reversed by addition of nanomolar concentrations of cAMP ( Ka = 40 nM ) , thus demonstrating that PrKX is a novel , type I cAMP dependent protein kinase that is activated at lower cAMP concentrations than the holoenzyme with the Calpha subunit of cAMP dependent protein kinase .
