TL;DR: In this article, a phage P1-mediated transduction and complementation analysis was performed to identify the target of the letD gene product, temperature-sensitive growth-defective mutants were screened from bacterial mutants that had escaped the growth inhibition that occurs in hosts carrying an FletA mutant.

TL;DR: The F plasmid of Escherichia coli was used to study the genetic background of the control circuit in the bacteria that co-ordinates DNA replication and cell division of the host cells as discussed by the authors.

TL;DR: The LetD and the LetA proteins constitute an opposing pair in modulating the DNA supercoiling activity of gyrase, probably by direct interaction.

TL;DR: Pseudomonas putida PpGl, which carries the CAM plasmid encoding enzymes involved in the degradation pathway of D- camphor, can utilize D-camphor as a sole carbon source and the total number of amino acids deduced from the nucleotide sequence is 422 for putidaredoxin reductase, and 106 for putIDaredoxin.

TL;DR: The genetic structure of the 42.84-43.6 F (BamHI-PstI) segment of the F Plasmid, which contains all the F DNA sequences necessary for coupling cell division of F+ bacteria with plasmid DNA replication, was analyzed by isolating a series of amber mutants.
