Fold: Phosphoenolpyruvate carboxykinase (ATP-oxaloacetate carboxy-liase)

consists of two alpa/beta domains
duplication: the domains share an unusual fold of 2 helices and 6-stranded mixed sheet; beta(2)-alpha-beta(4)-alpha; order 312465, strands 1 and 5 are antiparallel to the rest

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a/b)
   Mainly parallel beta sheets (beta-alpha-beta units)
