Genetic analysis of the tdcABC operon of Escherichia coli K-12.

abstract：:The gene coding for alveolysin, the thiol-activated toxin produced by Bacillus alvei, has been cloned by means of an oligonucleotide based on the known N-terminal sequence of the secreted protein. The complete nucleotide sequence of the gene has been determined. The deduced amino acid sequence of alveolysin shows that...
