Accession No. : 16 | PP2B
Pathway No. : 83 | 0 | 1000 | No | | Ca2.CaM.Ca4.CaNAB The CaM has only 2 calciums attached, but CaNAB has all 4. This contributes equally to enzyme activity along with the Ca3 and Ca4 forms. |

CaMCa2-CANAB acting as a Product in a reaction in Synaptic_Network Network
| 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 reaction are not consider. |

| | Based on Stemmer and Klee 1994 Biochem 33:6859-6866 This model is actually a simplification of the detail they report. In this model the Ca-binding affinity of CaM is not changed by binding to CaN. Rates here come from a detailed-balance argument. The reference rate is for CaMCa4 binding to CaNAB. This rate should be 1/2500 of that. |
