Family: Inositol polyphosphate kinase (IPK)

Pfam 03770

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: SAICAR synthase-like [56103]
    consists of two alpha+beta subdomains
  4. Superfamily: SAICAR synthase-like [56104]
    shares functional and structural similarities with the ATP-grasp fold and protein kinase superfamilies
