Reaction List for pathway HomoArginine (Pathway Number 309)

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.

  •   Binding of Homoarginine to Imidazole bound rat brainneuronal Nitric Oxide Synthase.Only Kd is known, Kf and Kb need to be approximatedaccordingly to match kinetic profiles. Due to lack of appropriate graphs the choice of Kf and Kb here is arbitrary and matches only the Kd. Kd = 10mM = 10000uM, Abu-Soud HM et al. Biochemistry. 1999 Sep 21;38(38):12446-51.
