    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

    The range of estimates found in the literature are: Km -> 40 - 150 uM (without NO) 20 - 40 uM (with NO) Vmax -> 10 - 100 nmol/mg/min (wihtout NO) 10 - 40 umol/mg/min (with NO). ----- thru personal correspondence from T. Bellamy, Wolfson Ins. for Biomedical Sciences, UK. NO increases the Vmax of sGC by 100-200 fold, and it has been proposed that this activation occurs subsequent to the binding of NO toa heme moiety on the enzyme. (Stone and Marletta,1995,Biochemistry,34:14668-14674).
