Targeting the Bacterial Orisome in the Search for New Antibiotics [PDF]
Frontiers in Microbiology, 2017 There is an urgent need for new antibiotics to combat drug resistant bacteria. Existing antibiotics act on only a small number of proteins and pathways in bacterial cells, and it seems logical that expansion of the target set could lead to development of

The orisome: structure and function [PDF]
Frontiers in Microbiology, 2015 During the cell division cycle of all bacteria, DNA-protein complexes termed orisomes trigger the onset of chromosome duplication. Orisome assembly is both staged and stringently regulated to ensure that DNA synthesis begins at a precise time and only ...

Changing Perspectives on the Role of DnaA-ATP in Orisome Function and Timing Regulation [PDF]
Frontiers in Microbiology, 2019 Bacteria, like all cells, must precisely duplicate their genomes before they divide. Regulation of this critical process focuses on forming a pre-replicative nucleoprotein complex, termed the orisome.

Blocking the Trigger: Inhibition of the Initiation of Bacterial Chromosome Replication as an Antimicrobial Strategy [PDF]
Antibiotics, 2019 All bacterial cells must duplicate their genomes prior to dividing into two identical daughter cells. Chromosome replication is triggered when a nucleoprotein complex, termed the orisome, assembles, unwinds the duplex DNA, and recruits the proteins ...

Low Affinity DnaA-ATP Recognition Sites in E. coli oriC Make Non-equivalent and Growth Rate-Dependent Contributions to the Regulated Timing of Chromosome Replication [PDF]
Frontiers in Microbiology, 2018 Although the mechanisms that precisely time initiation of chromosome replication in bacteria remain unclear, most clock models are based on accumulation of the active initiator protein, DnaA-ATP.

Blocking, Bending, and Binding: Regulation of Initiation of Chromosome Replication During the Escherichia coli Cell Cycle by Transcriptional Modulators That Interact With Origin DNA [PDF]
Frontiers in Microbiology, 2021 Genome duplication is a critical event in the reproduction cycle of every cell. Because all daughter cells must inherit a complete genome, chromosome replication is tightly regulated, with multiple mechanisms focused on controlling when chromosome ...

Link Between Antibiotic Persistence and Antibiotic Resistance in Bacterial Pathogens [PDF]
Frontiers in Cellular and Infection Microbiology, 2022 Both, antibiotic persistence and antibiotic resistance characterize phenotypes of survival in which a bacterial cell becomes insensitive to one (or even) more antibiotic(s).

Unique and universal features of Epsilonproteobacterial origins of chromosome replication and DnaA-DnaA box interactions [PDF]
Frontiers in Microbiology, 2016 In bacteria, chromosome replication is initiated by the interaction of the initiator protein DnaA with a defined region of a chromosome at which DNA replication starts (oriC).

Structure and Function of the Campylobacter jejuni Chromosome Replication Origin [PDF]
Frontiers in Microbiology, 2018 Campylobacter jejuni is the leading bacterial cause of foodborne infections worldwide. However, our understanding of its cell cycle is poor. We identified the probable C.
