  Kinetics same as GEF-bg_act-ras, but as of March 17, 2006, the kcat is scaled from 0.02 to 0.2 to have a stronger Ca response for the direct MAPK input.
3 Enzyme Activity:
GAP-inact-ras

Enzyme Molecule:

  From Eccleston et al JBC 268(36)pp27012-19 get Kd < 2uM, kcat - 10/sec From Martin et al Cell 63 843-849 1990 get Kd ~ 250 nM, kcat = 20/min I will go with the Eccleston figures as there are good error bars (10%). In general the values are reasonably close. k1 = 1.666e-3/sec, k2 = 1000/sec, k3 = 10/sec (note k3 is rate-limiting) 5 Nov 2002: Changed ratio term to 4 from 100. Now we have k1=8.25e-5; k2=40, k3=10. k3 is still rate-limiting.
