mixture of competitive and noncompetitive inhibition, binding to the substrate site excludes the substrate GTP, whereas binding to the noncompetitive site has no effect on GTP binding, although the resulting complex is catalytically inactive. It binds to the high and low affinity sites with equivalent affinities. BAY 41-2272, which shares an analogous core structure to YC-1, fully inhibits 2'-dADP binding to the low affinity site, whereas the inhibition by YC-1 is incomplete
