This model is based on Iwanaga T et al. Biochemistry (1999) 38(50):16629-35.The model features the catalytic activity of neuronal Nitric Oxide Synthase expressed in Escherichia coli in a four step reaction mechanism. The rates found in the model are used directly from their paper and have been determined from experiments performed at 25 C.

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.
