Segregation into and replication of plasmid deoxyribonucleic acid in chromosomeless segregants of Escherichia coli.
نویسنده
چکیده
The progeny cells of Escherichia coli strain P678-54, which normally do not contain deoxyribonucleic acid (DNA), were found to carry DNA when the parental cell carried colicin factor E1 (Col E1). The DNA found in the normally DNA-less segregants was shown to be Col E1 DNA, which is present primarily as a covalently closed circular molecule that can undergo more than one complete cycle of replication.

متن کاملTransformation of Salmonella typhimurium by plasmid deoxyribonucleic acid.
A modified transformation procedure that is effective for the introduction of plasmid deoxyribonucleic acid at high frequency into Salmonella typhimurium, as well as into Escherichia coli, is described. Transformed bacteria acquire a circular deoxyribonucleic acid species having the genetic and molecular characteristics of the transforming plasmid.

Introduction Phytase is an enzyme that has the ability to break down phytic acid into myoinositol and mineral phosphate, and widely uses as an additive in animal foods. The aim of this study was to achieve a high level of bacterial phytase expression in PET26b expression host. Materials and Methods To generate the recombinant phytase enzyme, the target gene was introduced into the expression ...
متن کاملConjugal deoxyribonucleic acid replication by Escherichia coli K-12: effect of nalidixic acid.
During the conjugal transfer of the R64-11 plasmid at 42 C from donor cells thermosensitive for vegetative deoxyribonucleic acid (DNA) synthesis to recipient minicells, the plasmids are conjugally replicated in the donor cells. This conjugal replication is inhibited by nalidixic acid, and the degree of inhibition is comparable to the reduction in the amount of plasmid DNA transferred to the rec...
متن کاملInfluence of protein and ribonucleic acid synthesis on the replication of the bacteriocinogenic factor Clo DF13 in Escherichia coli cells and minicells.
The influence of ribonucleic acid (RNA) and protein synthesis on the replication of the cloacinogenic factor Clo DF13 was studied in Escherichia coli cells and minicells. In chromosomeless minicells harboring the Clo DF13 factor, Clo DF13 deoxyribonucleic acid (DNA) synthesis is slightly stimulated after inhibition of protein synthesis by chloramphenicol or puromycin and continues for more than...
