1 The rate constants of the elementary steps of the p21 intrinsic GTPase activity and the GAP activated activity were similar between GTP and mantGTP. Guanosine Triphosphate H3 histone pseudogene 16 Homo sapiens
2 This is interpreted that the cleavage step of p21.GTP is preceded by and controlled by an isomerization of the p21.GTP complex. Guanosine Triphosphate H3 histone pseudogene 16 Homo sapiens
3 This is interpreted that the cleavage step of p21.GTP is preceded by and controlled by an isomerization of the p21.GTP complex. Guanosine Triphosphate H3 histone pseudogene 16 Homo sapiens
4 This is interpreted that the cleavage step of p21.GTP is preceded by and controlled by an isomerization of the p21.GTP complex. Guanosine Triphosphate H3 histone pseudogene 16 Homo sapiens
5 This is interpreted that the cleavage step of p21.GTP is preceded by and controlled by an isomerization of the p21.GTP complex. Guanosine Triphosphate H3 histone pseudogene 16 Homo sapiens
6 GAP accelerates the rate constant of the second fluorescence phase occurring with p21.mantGpp[NH]p. This result shows that GAP accelerates the proposed isomerization which limits GTP cleavage rather than the cleavage step itself. Guanosine Triphosphate H3 histone pseudogene 16 Homo sapiens
