Summary The kinetics of fat cell adenylyl cyclase were studied, with AMP-P(NH)P and Mn++ or Mg++ as the divalent cation. In general, the reaction times were not linear. In the presence of fluoride or GMP-P(NH)P, the time curves were concave upwards; in other cases (i.e., basal activity, insulin, or isoproterenol), transient rates tended to decrease with time during the assay. Kinetic data were analyzed according to a previously described procedure (Torreset al., 1978b) which isolates two kinetic components: initial and final. |
