| Kinetics are the same as for the craf_1* activity, ie., k1=5.5e-6, k2=0.42, k3 = 0.105 These are basedo n Force et al PNAS USA 91 1270-1274, 1994., but k1 is scaled up 5x (ie., Km is scaled down 5x to the value used here and for craf_1* activity: Km = 0.1591). |

| Same kinetics as other c-raf activated forms. See Force et al PNAS 91 1270-1274 1994. k1 = 1.1e-6, k2 = .42, k3 = 1.05 raise k1 to 5.5e-6 |

| Kinetics are the same as for the craf-1* activity, ie., k1=1.1e-6, k2=.42, k3 =0.105 These are based on Force et al PNAS USA 91 1270-1274 1994. These parms cannot reach the observed 4X stim of MAPK. So lets increase the affinity, ie, raise k1 10X to 1.1e-5 Lets take it back down to where it was. Back up to 5X: 5.5e-6 |
