Class Dephosphor1StepA_ICAff

java.lang.Object
  affectors.Affector
      affectors.Dephosphor1StepA_ICAff

All Implemented Interfaces:

java.lang.Cloneable

public class Dephosphor1StepA_ICAff

extends Affector

This is one half of an affector that dephosphorylates a single node at a speed determined by a phosphatase enzyme according to a sigmoid curve. Use this affector in the phosphorylated species. Use the B version in the product species. For either membrane-bound or cytoplasmic phosphatases, as long as target is cytoplasmic.

Formula
dSUBSTRATE_P/dt = -Pmax * SUBSTRATE_P * (PHOSPHO^nu / (K_PHOSPHO^nu + PHOSPHO^nu))

Parameters

Substrate [SUBSTRATE_P]	The unphosphorylated Node
Phosphotase [PHOSPHO]	The phosphatase Node.
Half-max activation [K_PHOSPHO_SUBSTRATE_P]	The concentration of phosphatase at which it de-phosphorylates at half its maximum rate.
Cooperativity [nu_PHOSPHO_SUBSTRATE_P]	The non-linearity in phosphatase activity as phosphatase concentration increases.
Max reaction rate [P_PHOSPHO]	The maximum reaction rate.
