The DnaA Cycle in Escherichia coli: Activation, Function and Inactivation of the Initiator Protein

open access: yesFrontiers in Microbiology, 2017
This review summarizes the mechanisms of the initiator protein DnaA in replication initiation and its regulation in Escherichia coli. The chromosomal origin (oriC) DNA is unwound by the replication initiation complex to allow loading of DnaB helicases ...

Initiation of chromosomal replication in predatory bacterium Bdellovibrio bacteriovorus

open access: yesFrontiers in Microbiology, 2016
Bdellovibrio bacteriovorus is a small Gram-negative predatory bacterium that attacks other Gram-negative bacteria, including many animal, human, and plant pathogens.

Control regions for chromosome replication are conserved with respect to both sequence and location between Escherichia coli strains

open access: yesFrontiers in Microbiology, 2015
In Escherichia coli, chromosome replication is initiated from oriC by the DnaA initiator protein associated with ATP. Three non-coding regions contribute to the activity of DnaA.

Cooperation between two modes for DNA replication initiation in the archaeon Thermococcus barophilus

open access: yesmBio
The mechanisms underpinning the replication of genomic DNA have recently been challenged in Archaea. Indeed, the lack of origin of replication has no deleterious effect on growth, suggesting that replication initiation relies on homologous recombination.

The Stringent Response Inhibits DNA Replication Initiation in E. coli by Modulating Supercoiling of oriC

open access: yesmBio, 2019
The stringent response enables bacteria to respond to a variety of environmental stresses, especially various forms of nutrient limitation. During the stringent response, the cell produces large quantities of the nucleotide alarmone ppGpp, which ...

Transcriptional Regulation Buffers Gene Dosage Effects on a Highly Expressed Operon in Salmonella

open access: yesmBio, 2018
Highly expressed genes are commonly located close to the origin of replication of bacterial chromosomes (OriC). This location skew is thought to reflect selective advantages associated with gene dosage effects during the replication cycle. The expression

A novel small molecule inhibitor of CD73 triggers immune-mediated multiple myeloma cell death

open access: yesBlood Cancer Journal
Highlights CD73 is the key ectoenzyme involved in the generation of AMP-derived adenosine, which contributes to immunosuppression in the MM BM milieu. Blocking CD73 activity with a potent, selective, orally bioavailable CD73 inhibitor ORIC-533 decreases ...

Role, Importance of ORIC and Entrepreneurship in Universities

open access: yesPakistan Journal of Medicine and Dentistry, 2020
The entrepreneurial universities aim to facilitate practical knowledge to students and industries to foster economic development. Many ideas were put forward to pioneer universities in the United States like Massachusetts Institute of Technology (MIT) and Stanford, and establish a solid patent policy, technology transfer policy and Liaison between ...

The Escherichia coli cryptic prophage protein YfdR binds to DnaA and initiation of chromosomal replication is inhibited by overexpression of the gene cluster yfdQ-yfdR-yfdS-yfdT

open access: yesFrontiers in Microbiology, 2016
The initiation of bacterial chromosomal replication is regulated by multiple pathways. To explore novel regulators, we isolated multicopy suppressors for the cold-sensitive hda-185 ΔsfiA(sulA) mutant.
