Abstract

The H-NOX (Heme-nitric oxide/oxygen binding) domain is conserved across eukaryotes and bacteria. In human soluble guanylyl cyclase (sGC) the H-NOX domain functions as a sensor for the gaseous signaling agent nitric oxide (NO). sGC contains the heme-binding H-NOX domain at its N-terminus, which regulates the catalytic site contained within the C-terminal end of the enzyme catalyzing the conversion of GTP (guanosine 5′-triphosphate) to GMP (guanylyl monophosphate). Here, we present the backbone and side-chain assignments of the 1H, 13C and 15N resonances of the 183-residue H-NOX domain from Nostoc sp. through solution NMR.
