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.
