Fold: Pyruvate kinase C-terminal domain-like

3 layers: a/b/a; mixed beta-sheet of 5 strands, order 32145, strand 5 is antiparallel to the rest

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a/b)
   Mainly parallel beta sheets (beta-alpha-beta units)
3. Fold: Pyruvate kinase C-terminal domain-like
   3 layers: a/b/a; mixed beta-sheet of 5 strands, order 32145, strand 5 is antiparallel to the rest

Superfamilies:

1. Pyruvate kinase, C-terminal domain (1)
2. ATP syntase (F1-ATPase), gamma subunit (1)
   contains an antiparallel coiled coil formed by N- anb C-terminal extensions to the common fold
