B) The Schiff base of Lys165 with pyruvate (4AH7).
Comparison of the E. coli (PDB ID: 2WNN)  and S. aureus (4AH7) enzymes in complex with pyruvate showed that the pyruvate is covalently linked to the enzyme as a Schiff base and makes identical interactions with the backbone amides of Ser48 and Ser49 and also with the side-chain hydroxyl group of Ser49 (equivalent to Ser47 and Thr48 in the E. coli enzyme; Figure 3 A and B).
In addition, the structure of the enzyme–pyruvate complex (PDB ID: 4AH7) was also determined.
