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

link to SUPERFAMILY database - Superfamily

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
  4. Superfamily: Ligand-binding domain in the NO signalling and Golgi transport [111126]

Families:

  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
    1. Methyl-accepting chemotaxis protein [111128]
      1. Thermoanaerobacter tengcongensis [TaxId: 119072] [111129] (4) picpic
        SQ Q8RBX6 1-191
  2. TRAPP components [118076] (2)
    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
    1. Trafficking protein particle complex subunit 3, Bet3 homolog [118077]
      covalently linked long fatty acid occupies the ligand-binding cavity
      1. Mouse (Mus musculus) [TaxId: 10090] [118078] (3) picpic
        SQ O55013 9-173
    2. TRAPPC5, similar to trafficking protein particle complex 5 [160687]
      1. Zebrafish (Brachydanio rerio) [TaxId: 7955] [160688] (2) picpic
        SQ Q6DGL5 21-188
  3. MJ1460-like [160689] (1)
    C-terminal part corresponds to Pfam 02830; V4R (vinyl 4 reductase) domain
    1. Hypothetical protein MJ1460 [160690]
      1. Methanococcus jannaschii [TaxId: 2190] [160691] (2) picpic
        SQ Q58855 5-156
