Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
sGC_Stone_ Marletta	15	Pathway	sGC
This features the two step binding of NO to soluble Guanylyl Cyclase as proposed by Stone JR, Marletta MA. Biochemistry (1996) 35(4):1093-9. There is a fast step binding scheme and a slow step binding scheme. The difference lies in the binding of a NO to a non-heme site on sGC, which may not necessarily be the same site of binding during the initial binding. The rates have been directly used from their models

NO.sGCfast acting as a Substrate in a reaction in  sGC_Stone_Marletta 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.

This is the fast binding of NO to sGC, subsequently activating it, as proposed by Stone and Marletta. Rates of these binding reactions used directly from Stone and Marletta,1996, Biochemistry, 35(4):1093-1099, based on whose paper this model is made. Rates obtained from stopped flow kinetics detailed in their paper.
