| 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. | |||

L-Arg acting as a Substrate in a reaction in NOS_Iwanaga Network
| 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. |
