The HNOB (Haem NO Binding) domain, is a predominantly alpha-helical domain and binds heme via a covalent linkage to histidine. It is a haem protein sensor (SONO) that displays femtomolar affinity for nitrous oxide, NO [3]. It is predicted to function as a haem-dependent sensor for gaseous ligands and to transduce diverse downstream signals in both bacteria and animals.	Domain
