Family: mRNA capping enzyme

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: ATP-grasp [56058]
    Consists of two subdomains with different alpha+beta folds
    shares functional and structural similarities with the PIPK and protein kinase superfamilies
  4. Superfamily: DNA ligase/mRNA capping enzyme, catalytic domain [56091]
    has a circularly permuted topology
