Caulobacter crescentus mRNA half-lives by rifampicin transcription shutoff

Project description:mRNA half-life profiling in the bacterium Caulobacter crescentus was preformed by shutting of transcription with the antibiotic rifampicin, and following mRNA abundance at 1, 2, 4, 8, and 15 minutes post rifampicin. All RNA measurements were performed on cells grown to mid-log in M2G minimal growth medium. Two biological replicates time coursees were collected from independent starter cultures.

Expression analysis of Caulobacter crescentus NA1000 Plac::CCNA_00382 (ccrM) vs Caulobacter crescentus

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. References of strains: CcrMOE: Collier, J. and Shapiro, L. (2009) Feedback control of DnaA-mediated replication initiation by replisome-associated HdaA protein in Caulobacter.

A six chip study using total RNA recovered from three separate wild-type cultures of Caulonacter crescentus NA1000 and three separate cultures of a triple mutant strain, Caulonacter crescentus NA1000 Plac::CCNA_00382 (ccrM), in which the ccrM gene coding for a DNA methyltransferase methylating the adenine in GANTC motifs is truncated and its product inactive. Each chip measures the expression level of 3933 genes from Caulobacter crescentus NA1000 with 3 probes per gene and with three-fold technical redundancy.

Comparison of CcrM-dependent methylation in Caulobacter crescentus and Brucella abortus by nanopore sequencing

Project description:Bacteria rely on DNA methylation for restriction modification systems and for epigenetic control of gene expression. In Alphaproteobacteria, the CcrM orphan methyltransferase is particularly noteworthy in a range of transcriptional regulation. The wider adoption of nanopore sequencing and updated processing pipelines has made epigenome measurements in bacteria more convenient than before. Here, we validate this approach in Alphaproteobacteria by measuring CcrM-dependent DNA methylation in Caulobacter crescentus and show excellent correlation with other approaches. Continuing in Caulobacter, we directly measure the impact of Lon-mediated CcrM degradation on the epigenome and show that the AlkB demethylase has no global impact on DNA methylation during normal growth. We report on the global DNA methylation in Brucella abortus for the first time and find that CcrM-dependent methylation is reliant on Lon in an unexpected species- and chromosome-specific manner. Finally, we measure the impact of the MucR transcription factor on the Brucella methylome. Given the ease and reduced costs, our work demonstrates the utility of nanopore-based sequencing for epigenome monitoring in Alphaproteobacteria.

Expression analysis of Caulobacter crescentus NA1000 delta-CCNA_00382 (ccrM) [DccrM] vs Caulobacter crescentus NA1000 wild type [WT]

Project description:Investigation of whole genome gene expression level changes in a Caulobacter crescentus NA1000 delta-CCNA_00382 (ccrM) mutant, compared to the wild-type strain. The mutations engineered into this strain render it incapable of methylating its genome on the adenine at GANTC motifs.

Caulobacter crescentus flagellins glycopeptides analyses

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.
