Member Function Documentation

RateTerm* MMEnzyme1::copyWithVolScaling ( double  vol, double  sub, double  prd  ) const

inlinevirtual

Duplicates rate term and then applies volume scaling. Arguments are volume of reference voxel, product of vol/refVol for all substrates: applied to R1 product of vol/refVol for all products: applied to R2

Note that unless the reaction is cross-compartment, the vol/refVol will be one.

Implements RateTerm.

        {
            double ratio = vol * sub * NA;
            return new MMEnzyme1( ratio * Km_, kcat_, enz_, sub_);
        }

Here is the call graph for this function:

unsigned int MMEnzyme1::getReactants ( vector< unsigned int > &  molIndex ) const

inlinevirtual

This function finds the reactant indices in the vector S. It returns the number of substrates found, which are the first entries in molIndex. The products are the remaining ones. Note that it does NOT find products for unidirectional reactions, which is a bit of a problem.

Implements RateTerm.

            molIndex[1] = sub_;
            return 2;
        }

double MMEnzyme1::operator() ( const double *  S ) const

inlinevirtual

Computes the rate. The argument is the molecule array.
