Superfamily: RraA-like

structural similarity and possible distant homology to the phosphohistidine domain of pyruvate phosphate dikinase
link to SUPERFAMILY database - Superfamily

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: The "swivelling" beta/beta/alpha domain [52008]
    3 layers: b/b/a; the central sheet is parallel, and the other one is antiparallel; there are some variations in topology
    this domain is thought to be mobile in most multi-domain proteins known to contain it
  4. Superfamily: RraA-like [89562]
    structural similarity and possible distant homology to the phosphohistidine domain of pyruvate phosphate dikinase
    link to SUPERFAMILY database - Superfamily
