Unbalanced Growth, the DNA Replication Cycle and Discovery of Repair Replication

open access: yesLife, 2023
This article recounts my graduate research at Yale University (1954–1958) on unbalanced growth in Eschericia coli during thymine deprivation or following ultraviolet (UV) irradiation, with early evidence for the repair of UV-induced DNA damage. Follow-up

Bi-modal distribution of the second messenger c-di-GMP controls cell fate and asymmetry during the caulobacter cell cycle [PDF]

open access: yes, 2013
Many bacteria mediate important life-style decisions by varying levels of the second messenger c-di-GMP. Behavioral transitions result from the coordination of complex cellular processes such as motility, surface adherence or the production of virulence ...

Insights into the activation mechanism of PopA, a cyclic di-GMP effector protein involved in cell cycle and development of "Caulobacter Crescentus" [PDF]

open access: yes, 2012
In Caulobacter crescentus, a complex network integrating cyclic di-GMP and Phosphorylation-dependent signals controls the proteolysis of key regulatory proteins to drive cell cycle and polar morphogenesis.

Analysis of cyclic di-GMP signaling components in "caulobacter crescentus" behavior and cell cycle control [PDF]

open access: yes, 2013
Cell cycle progression and polar morphogenesis in Caulobacter crescentus are coordinated by the interplay of multiple proteins in time and space. One major regulatory factor is the second messenger cyclic di-GMP (c-di-GMP) therefore especially the ...

Phosphotransferase-dependent accumulation of (p)ppGpp in response to glutamine deprivation in Caulobacter crescentus

open access: yesNature Communications, 2016
The small molecule (p)ppGpp is commonly produced by bacteria as a signal of nutrient starvation. Here, Ronneau et al. show that (p)ppGpp accumulation in the model bacterium Caulobacter crescentusis modulated by a nitrogen-related phosphotransferase ...

Prokaryotic ParA–ParB–parS system links bacterial chromosome segregation with the cell cycle [PDF]

open access: yes, 2012
While the essential role of episomal par loci in plasmid DNA partitioning has long been appreciated, the function of chromosomally encoded par loci is less clear. The chromosomal parA–parB genes are conserved throughout the bacterial kingdom and encode

Metabolic control of cell division in α-proteobacteria by a NAD-dependent glutamate dehydrogenase

open access: yesCommunicative & Integrative Biology, 2016
Prior to initiate energy-consuming processes, such as DNA replication or cell division, cells need to evaluate their metabolic status. We have recently identified and characterized a new connection between metabolism and cell division in the α ...

Cell-cycle inhibition by Helicobacter pylori L-asparaginase. [PDF]

open access: yesPLoS ONE, 2010
Helicobacter pylori (H. pylori) is a major human pathogen causing chronic gastritis, peptic ulcer, gastric cancer, and mucosa-associated lymphoid tissue lymphoma.

Activation and polar sequestration of PopA, a c-di-GMP effector protein involved in Caulobacter crescentus cell cycle control [PDF]

open access: yes, 2014
When Caulobacter crescentus enters S-phase the replication initiation inhibitor CtrA dynamically positions to the old cell pole to be degraded by the polar ClpXP protease.

Cyclic di-GMP mediates a histidine kinase/phosphatase switch by noncovalent domain cross-linking [PDF]

open access: yes, 2016
Histidine kinases are key components of regulatory networks in bacteria. Although many of these enzymes are bifunctional, mediating both phosphorylation and dephosphorylation of downstream targets, the molecular details of this central regulatory switch ...
