Pathway No. : 335 | 0.5 | 1.5 | No | | Couldn't find any ref to the actual conc of craf-1 but I should try Strom et al Oncogene 5 pp 345 In line with the other kinases in the cascade, I estimate the conc to be 0.2 uM. To init we use 0.15, which is close to equil 16 May 2003: Changing to synaptic levels. Increasing 2.5 fold to 0.5 uM.

| | Rate consts from Chen et al Biochem 32, 1032 (1993) k3 = k2 = 4 k1 = 9e-5 recalculated gives 1.666e-5, which is not very different. Looks like k3 is rate-limiting in this case: there is a huge amount of craf locked up in the enz complex. Let us assume a 10x higher Km, ie, lower affinity. k1 drops by 10x. Also changed k2 to 4x k3. Lowerd k1 to 1e-6 to balance 10X DAG sensitivity of PKC 3 Aug 2004. Lowered Km from 66.66 to 3.33, to match that of PKC-inact-GAP |
