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
