Prozymes: A systematic screening strategy to discover new promiscuous carbonyl-transformation activities in 4oxalocrotonate tautomerase (4-OT) is reported. The N-terminal proline of this enzyme provides a chemical functionality in the active site that might be suitable for enamine catalysis. It is shown that the aldol condensation of acetaldehyde with benzaldehyde is catalyzed by 4-OT.
