title: The complete nucleotide sequence of the gene coding for botulinum type C1 toxin in the C-ST phage genome.
abstract: Two DNA fragments, 3 kbp and 7.8kbp, which encode the type C1 botulinum neurotoxin gene, were obtained from toxigenic bacteriophage DNA by treatment with a restriction enzyme. They were cloned into the plasmid vectors for nucleotide sequence determination. The nucleotide sequence contained a single open reading frame coding for 1,291 amino acids corresponding to a polypeptide with a molecular weight of 149,000. The amino acid sequence of the C1 toxin has a few regions highly homologous with tetanus toxin.
