package affectors; import main.Node; import main.Globals; /**Diploid version of CleaveageB_ICAff. Reduces to same result if the two alleles are * identical. Assumptions for diploidizing: (1) Two alleles catalyze reactions instantly * so there's no chance that one allele is able to bind and not cleave (thus inhibiting * the other). (2) There is no synergy or cooperativity between the two (i.e. the two * alleles don't see each other or interact) and the total activity is simply the sum of * the individual activities. It would be interesting to compare this * where the nonlinearity depends on some function of the sum of the concentrations * *
This is one half of an affector that cleaves a single node into two other * nodes. Use this affector in each of the product species. Use the A version in the * uncleaved species. *
Formula
*
dNODEX/dt = 0.5*SUBSTRATE(CMax1 * ( (ACTIVATOR1 ^ nu1) / ( K1 ^ nu1 + ACTIVATOR1 ^ nu1) )+
* CMax2 * ( (ACTIVATOR2 ^ nu2) / ( K2 ^ nu2 + ACTIVATOR2 ^ nu2) )
*
*
Parameters *
Substrate [SUBSTRATE] | The uncleaved Node |
Activator1 [ACTIVATOR1] | The regulator Node allele 1 which is activating cleavage |
Activator1 [ACTIVATOR1] | The regulator Node allele 2 which is activating cleavage |
Kappa1 [K_ACTIVATOR1_SUBSTRATE] | The level of the activator allele 1 at * which it acts half-maximally. |
Kappa2 [K_ACTIVATOR2_SUBSTRATE] | The level of the activator allele 2 at * which it acts half-maximally. |
nu1 [nu_ACTIVATOR1_SUBSTRATE] | Cooperativity of the activation allele 1. |
nu2 [nu_ACTIVATOR2_SUBSTRATE] | Cooperativity of the activation allele 2. |
CMax1 [CMax1_SUBSTRATE] | Maximal rate of cleavage for allele 1. |
CMax2 [CMax2_SUBSTRATE] | Maximal rate of cleavage for allele 2. |
