Abstract

The nucleotide sequence of a 3780‐base pair segment of DNA containing the aceE gene encoding the pyruvate dehydrogenase component (E1) of the pyruvate dehydrogenase complex of Escherichia coli, has been determined by the dideoxy chain‐termination method. The aceE structural gene comprises 2655 base pairs (885 codons, excluding the initiation codon AUG), it is preceded by a good ribosome binding site and several potential RNA polymerase binding sites. Its polarity and location in the restriction map of the corresponding segment of DNA are consistent with it being the proximal gene in the ace operon, as defined in previous genetic and post‐infection labelling studies. The relative molecular mass (99474), composition (885 amino acids), amino‐terminal residue and carboxy‐terminal sequence predicted from the nucleotide sequence are in excellent agreement with published information obtained from studies with the purified pyruvate dehydrogenase component (E1).

The nucleotide sequence also contains a second gene (gene A) situated upstream of the aceE gene. It appears to be an independent gene containing 708 base pairs (236 codons) and encoding a weakly expressed product (protein A; Mr= 27049) of unknown function
