at the sorocarp stage of differentiation , the dominant role of adenylate kinase activity is indicated by the observations that ( i ) adenylate kinase activity was found to be present , ( ii ) the specific radioactivities of the beta- and gamma-phosphates of atp were equal , ( iii ) the increase in specific radioactivity of adenosine diphosphate was one-half that of atp in the presence of [ ( 32 ) p ] pi , and ( iv ) the steady-state equilibrium constant calculated ( 0.69 ) from the nucleotide levels equaled that of the apparent equilibrium constant reported in the literature ( 0.70 ) .
