Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: Protein kinase-like (PK-like) [56111]
    consists of two alpha+beta domains, C-terminal domain is mostly alpha helical

Superfamilies:

  1. Protein kinase-like (PK-like) [56112] (7)
