The model contains one compartment called C. There are four species called X0, X1, T and S1 and two parameters called k1 and k3. The model contains two reactions defined as:
Reaction | Rate |
X0 → T | C · k · X0 |
T → X1 | C · k · S1 |
Reaction T → X1 defines one local parameter k which has a scope local to the defining reaction and is different from the global parameter k used in reaction X0 → T.
The model contains two rules:
Type | Variable | Formula |
Algebraic | n/a | (1 + k3) · S1 − T |
assignmentRule | k | 0.1 |
The assignment rule assigns a value to parameter k which has no value attributed to it by the model definition. The calculated value should be used.
The initial conditions are as follows:
Value | Units | |
Initial amount of X0 | 1 | mole |
Initial amount of X1 | 0 | mole |
Initial amount of T | 0 | mole |
Initial amount of S1 | 0 | mole |
Value of parameter k | undeclared | second-1 |
Value of parameter k3 | 2.5 | dimensionless |
Value of local parameter k | 0.375 | second-1 |
Volume of compartment C | 1 | litre |
The species values are given as amounts of substance to make it easier to use the model in a discrete stochastic simulator, but (as per usual SBML principles) their symbols represent their values in concentration units where they appear in expressions.
