CellML structure (CellML 1.1 spec)
- Component: ActivatedPromoter
- Units:
- Imported from Environment component
- Variables:
- nbGeneCopies (public interface = in / init value = 1.0)
- maxTranscriptionRate (public interface = none / init value = XXX)
- K (dissociation-constant) (public interface = none / init value = XXX)
- n (Hill-coefficient) (public interface = none / init value = XXX)
- activator (public interface = in )
- PoPsOUT (public interface = out / init value = 0.)
- MathML
- <amsmath>PoPsOUT = \frac{nbGenesCopies*maxTranscriptionRate*[activator]^{n}}{K^{n} + [activator]^{n}}</amsmath>
