Having previously determined the complete amino acid sequence of 2-keto-4-hydroxyglutarate aldolase from Escherichia coli (C. J. Vlahos and E. E. Dekker, J. Biol. Chem. 263:11683-11691, 1988), we amplified the gene that codes for this enzyme by the polymerase chain reaction using synthetic degenerate deoxyoligonucleotide primers. The amplified DNA was sequenced by subcloning the polymerase chain reaction products into bacteriophage M13; the nucleotide sequence of the gene was found to be in exact agreement with the amino acid sequence of the gene product. Overexpression of the gene was accomplished by cloning it into the pKK223.3 expression vector so that it was under control of the tac promoter and then using the resultant plasmid, pDP6, to transform E. coli DH5 alpha F'IQ. When this strain was grown in the presence of isopropyl beta-D-thiogalactopyranoside, aldolase specific activity in crude extracts was 80-fold higher than that in wild-type cells and the enzyme constituted approximately 30% of the total cellular protein. All properties of the purified, cloned gene product, including cross-reactivity with antibodies elicited against the wild-type enzyme, were identical with the aldolase previously isolated and characterized. A strain of E. coli in which this gene is inactivated was prepared for the first time by insertion of the kanamycin resistance gene cartridge into the aldolase chromosomal gene. << Less
