Reaction List for pathway NOS (Pathway Number 90)

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 reactions is not considered.

  Those binding CaM have a high Kd, including nNOS, ~<=10nM. The binding of CaM to nNOS has been demonstrated to act as the trigger necessary for electron transfer and catalytic activity. (Marletta, Biochemistry, 1997;36:12337-12345).
