Substrate selectivity and biochemical properties of 4-hydroxy-2-keto-pentanoic acid aldolase from Escherichia coli.
4-Hydroxy-2-keto-pentanoic acid aldolase from Escherichia coli was identified as a class I aldolase. The enzyme was found to be highly selective for the acetaldehyde acceptor but would accept alpha-ketobutyric acid or phenylpyruvic acid in place of the pyruvic acid carbonyl donor.
