RESUMO
Deoxyribonucleic acid fragments bearing the gene for diphtheria toxin have been identified in restriction enzyme digests of deoxyribonucleic acids from beta-converting and gamma-nonconverting corynebacteriophages. A combination of physical and genetic evidence has established that the Bam HI band C fragment of beta phage deoxyribonucleic acid, which carries the specific phage attachment site (Buck and Groman, J. Bacteriol. 148:131-142, 1981), also carries most, and probably all, of the gene for diphtheria toxin. A detailed restriction map of this tox-bearing Bam HI fragment has been developed, and the locations and orientation of the tox gene and the attP site within this fragment have been established.
