RESUMO
Clo DF13 plasmid deoxyribonucleic acid (DNA) was used as a template to direct transcription and translation in a DNA-dependent cell-free system prepared from Escherichia coli. Analysis of the invitro products on sodium dodecylsulfate-polyacrylamide gels revealed that Clo DF13 DNA directs the synthesis of at least 10 polypeptides ranging in molecular weight from approximately 7,000 to 70,000. Two of these polypeptides could be identified, with respect to their physiochemical and biological characteristics, as the products of the Clo DF13 genes coding for cloacin DF13 and Clo DF13 immunity protein. These results confirm previous findings, obtained which Clo DF13-harbouring minicells of E. coli, that the structural tenes for the latter proteins residue on the Clo DF13 genome.
