Fold: PK beta-barrel domain-like

barrel, closed; n=7, S=10; complex topology

Lineage:

1. Root: scop
2. Class: All beta proteins
3. Fold: PK beta-barrel domain-like
   barrel, closed; n=7, S=10; complex topology

Superfamilies:

1. PK beta-barrel domain-like (2)
   1. Pyruvate kinase beta-barrel domain (6)
      this domain interrupts beta/alpha-barrel domain
      C-terminal domain is alpha/beta
   2. ATP sulfurylase N-terminal domain (3)
      incomplete barrel of 6 strands, the last PK strand is missing
