Project description:Investigation of whole genome gene expression level changes in a Caulonacter crescentus NA1000 Plac::CCNA_00382 (ccrM) mutant, compared to the wild-type strain. The mutations engineered into this strain cause the CcrM DNA methyltransferase to be overexpressed and the chromosome to be constitutively methylated at the adenine at GANTC motifs.

Project description:Caulobacter crescentus is an alphaproteobacterium that divides assymetrically. Each cell cycle results in the production of a motile flagellated cell and a sessile cell called the swamer cell and the stalked cell, respectively. The flagellar filament is composed of thousands polymerized flagellins. We showed that glycosylation of flagellins is required for the assembly of the flagellum. This glycosylation is performed by soluble FlmG glycosyltransferases that transfer nonulosonic acids (pseudaminic acid or legionaminic acid) directly to the flagellins. Such glycosylation system is also present in a close relative of Caulobacter crescentus, Brevundimonas subvibrioides. The project is to identify the site of glycosylation and the potential sugar added on this site.

Project description:Investigation of whole genome gene expression level changes in a Caulobacter crescentus NA1000 dcdnL mutant, compared to the wild-type strain. In bacteria, transcription of housekeeping genes required for metabolic homeostasis and cell proliferation is guided by the sigma factor σ70. The conserved CarD-like transcriptional regulator, CdnL, associates with promoter regions where σ70 localizes and stabilizes the open promoter complex. Caulobacter crescentus cells lacking CdnL have severe morphological and growth defects. Our microarray experiment demonstrates how cdnL deletion affects the transcriptome of Caulobacter crescentus.

Project description:Antibiotic persistence is a transient phenotypic state during which a bacterium can withstand otherwise lethal antibiotic exposure or environmental stresses. In Escherichia coli, persistence is promoted by the HipBA toxin-antitoxin system. The HipA toxin functions as a serine/threonine kinase that inhibits cell growth, while the HipB antitoxin neutralizes the toxin. E. coli HipA inactivates the glutamyl-tRNA synthetase GltX, which inhibits translation and triggers the highly conserved stringent response. Although hipBA operons are widespread in bacterial genomes, it is unknown if this mechanism is conserved in other species. Here we describe the functions of three hipBA modules in the alpha-proteobacterium Caulobacter crescentus. The HipA toxins have different effects on growth and macromolecular syntheses, and they phosphorylate distinct substrates. HipA1 and HipA2 contribute to antibiotic persistence during stationary phase by phosphorylating the aminoacyl-tRNA synthetases GltX and TrpS. The stringent response regulator SpoT is required for HipA-mediated antibiotic persistence, but persister cells can form in the absence of all hipBA operons or spoT, indicating that multiple pathways lead to persister cell formation in C. crescentus.
