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

Superfamilies:

  1. Ligand-binding domain in the NO signalling and Golgi transport [111126] (3)
    link to SUPERFAMILY database - Superfamily
    1. H-NOX domain [111127] (1) picpic
      binds heme between the N-terminal 4-helical bundle and the C-terminal alpha-beta(2)-alpha-beta(2) subdomains
    2. TRAPP components [118076] (2) picpic
      Pfam 04051; form homo- and hetero-dimers with the first two helices of one subunit complementing the fold of the other subunit to the H-NOX domain fold
    3. MJ1460-like [160689] (1) picpic
      C-terminal part corresponds to Pfam 02830; V4R (vinyl 4 reductase) domain
