Pyruvate Kinase Structure
Pyruvate kinase (1pkn.pdb) is the last enzyme in the glycolytic pathway. This multidomain protein is a tetramer; only one subunit is shown here. The structure is from rabbit muscle.

The starting Display is Cartoons; the Color is Group.
The amino and carboxyl termini of the protein are labeled.
Viewing Tip: Note the similarity between the central 8-stranded a/b barrel domain of pyruvate kinase to the structure of triose phosphate isomerase.
