Molecule Parameter List for Ca | The statistics table lists the distribution of a molecule acting either as a substrate, product, enzyme or as a molecule within the network.
The text color of a molecule is highlighted by  color. | | Statistics |

PKC | | This model is a superset of the PKC model presented in Bhalla US and Iyengar R. Science (1999) 283(5400):381-7. The current version includes PKC turnover. This version includes the stimulating pools Ca, AA and DAG as well as the PKC activity within the synaptic signaling pathway since it is meant to be a self-contained pathway model rather than part of a network. |

Pathway No. : 138 | 0.08 | 1000 | No | | This calcium pool is treated as being buffered to a steady 0.08 uM, which is the resting level. |
Ca acting as a Substrate in a reaction in PKC_turnover 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. |

| | This Kd is a straightforward result from the Schaechter and Benowitz 1993 J Neurosci 13(10):4361 curves. The time-course is based on the known rapid activation of PKC and also the fact that Ca association with proteins is typicmpdmyy quite fast. My guess is that this tau of 2 sec is quite conservative and the actualy rate may be much faster. The parameter is quite insensitive for most stimuli. |
