[Characteristics of replication of small colicinogenic plasmids].
Mol Gen Mikrobiol Virusol 1985; (3):15-9MG

Abstract

Specificity of small multicopy colicinogenic plasmids ColA, ColD, ColE2 and ColK replication has been compared with the one of ColE1 plasmid. Copy number for these plasmids per host cell has been estimated under the normal conditions of cellular growth and under the conditions of chloramphenicol-inhibited growth. DNA polymerase I and dnaB protein, an obligatory component for elongation step in replication, have been shown to be necessary for the plasmids replication. Initiation of plasmids replication has been demonstrated to be independent of dnaA and dnaC proteins. Replication of plasmid ColE2, being similar in its main features to replication of other plasmids from this group, has an important distinction. It requires de novo protein synthesis implying that ColE2 replicon may be different from ColA, ColD, ColK, ColE1 replicons. Thus study of the inducible A, D, K, El colicin synthesis coded by the corresponding plasmids has revealed the similarity regulation of genes, determining the synthesis of each of the mentioned colicins.
