| This is a network model of many pathways present at the neuronal synapse. The network has properties of temporal tuning as well as steady-state computational properties. In its default form the network is bistable.Bhalla US Biophys J. 2004 Aug;87(2):745-53 | |||

| MAPKK | 2003 Accession No. : 50 | MAPK Pathway No. : 211 | 0.18 | 1000 | No | |
| Conc is from Seger et al JBC 267:20 pp14373 (1992) mwt is 45/46 Kd We assume that phosphorylation on both ser and thr is needed for activiation. See Kyriakis et al Nature 358 417 1992 Init conc of total is 0.18 | ||||||
MAPKK acting as a Substrate for an Enzyme in MAPK_network_2003 Network
| Enzyme Molecule / Enzyme Activity | Accession Name | Pathway Name | Km (uM) | kcat (s^-1) | Ratio | Enzyme Type | Reagents |
| Raf-GTP-Ras* / Raf-GTP-Ras*.1 | 2003 Accession No. : 50 | MAPK Pathway No. : 211 | 0.159091 | 0.105 | 4 | explicit E-S complex | Substrate MAPKK Product MAPKK-ser |
| 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 | |||||||
