Class c: Alpha and beta proteins (a/b) [51349] (141 folds) |
Fold c.92: Chelatase-like [53799] (2 superfamilies) duplication: tandem repeat of two domains; 3 layers (a/b/a); parallel beta-sheet of 4 strands, order 2134 |
Superfamily c.92.2: "Helical backbone" metal receptor [53807] (4 families) contains a long alpha helical insertion in the interdomain linker |
Family c.92.2.3: Nitrogenase iron-molybdenum protein [53816] (2 proteins) 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 |
