Reaction List for pathway Ras (Pathway Number 1019)

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reactions is not considered.

  We have no numbers for this. It is probably between the two extremes represented by the CaMKII phosph states, and I have used guesses based on this. kf=1e-4 kb=1 The reaction is based on Farnsworth et al Nature 376 524-527 1995 28 Feb 2006: Increased affinity 36-fold to account for Ca input to MAPK cascade, possibly folding in other pathway inputs. 21 April 2006: Altered affinity to same level as pkm_mapk21.g model to prevent spontaneous turnon. Kf = 200, Kb = 1.

  This is extremely slow (1e-4), but it is significant as so little GAP actually gets complexed with it that the total GTP turnover rises only by 2-3 X (see Gibbs et al, JBC 265(33) 20437-20422) and Eccleston et al JBC 268(36) 27012-27019 kf = 1e-4
