Nitric oxide (NO)-sensitive (soluble) guanylyl cyclase (GTP diphosphate-lyase (cyclising)), E.C. 4.6.1.2, is a heterodimer comprising a β1 subunit and one of two alpha subunits (α1, α2) giving rise to two functionally indistinguishable isoforms, GC-1 (α1β1) and GC-2 (α2β1) [8,13]. A haem group is associated with the β subunit and is the target for the endogenous ligand NO, and, potentially, carbon monoxide [3]. The enzyme converts guanosine-5'-triphosphate to the intracellular second messenger cyclic guanosine-3',5'-monophosphate (cyclic GMP).

ODQ also shows activity at other haem-containing proteins [1], while YC-1 may also inhibit cGMP-hydrolysing phosphodiesterases [2,4].
