Family: DsrA/DsrB N-terminal-domain-like

Dissimilatory sulfite reductase is a heterodimer of homologous DsrA and DsrB subunits, the assembly of which is similar to the architecture of duplicated sulfite reductase CysI

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: Ferredoxin-like [54861]
    alpha+beta sandwich with antiparallel beta-sheet; (beta-alpha-beta)x2
  4. Superfamily: Nitrite/Sulfite reductase N-terminal domain-like [55124]
    duplication: contains two subdomains of this fold
