Fold: Ligand-binding domain in the NO signalling and Golgi transport

an N-terminal helical bundle and the C-terminal alpha-beta(2)-alpha-beta(2) subdomain enclose a ligand-binding cavity

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a+b) [53931]
   Mainly antiparallel beta sheets (segregated alpha and beta regions)
3. Fold: Ligand-binding domain in the NO signalling and Golgi transport [111125]
   an N-terminal helical bundle and the C-terminal alpha-beta(2)-alpha-beta(2) subdomain enclose a ligand-binding cavity

   uperfamily
   1. H-NOX domain [111127] (1)
      binds heme between the N-terminal 4-helical bundle and the C-terminal alpha-beta(2)-alpha-beta(2) subdomains
