Protein: Nitrogenase iron-molybdenum protein, beta chain from Klebsiella pneumoniae [TaxId: 573]

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: Chelatase-like [53799]
    duplication: tandem repeat of two domains; 3 layers (a/b/a); parallel beta-sheet of 4 strands, order 2134
  4. Superfamily: "Helical backbone" metal receptor [53807]
    contains a long alpha helical insertion in the interdomain linker
    link to SUPERFAMILY database - Superfamily
  5. Family: Nitrogenase iron-molybdenum protein [53816]
    contains three domains of this fold; "Helical backbone" holds domains 2 and 3
    both chains are homologous; the inter-chain arrangement of domains 1 is similar to the intra-chain arrangement of domains 2 and 3
  6. Protein: Nitrogenase iron-molybdenum protein, beta chain [81401]
    both chains are homologous; the inter-chain arrangement of domains 1 is similar to the intra-chain arrangement of domains 2 and 3
  7. Species: Klebsiella pneumoniae [TaxId: 573] [81399]
