DOI: 10.1002/bab.2390
Abstract: The bacterium Caulobacter crescentus secretes an adhesive polysaccharide called holdfast, which is the known strongest underwater adhesive in nature. The deacetylase encoded by hfs (holdfast synthesis) H gene is a key factor affecting the adhesion… read more here.

DOI: 10.1021/acsnano.4c17885
Abstract: Bacterial outer membrane vesicles (OMVs) are an emerging and attractive technology for the generation of vaccines. Their properties as natural adjuvants, size, acellularity, and comparative cost of production favor their use as vaccines. Two major… read more here.

DOI: 10.1038/s41467-025-65274-1
Abstract: In bacteria, regulatory networks controlling the adaptation of gene expression in response to stress are frequently complemented by base-pairing small regulatory RNAs (sRNAs) that act at the post-transcriptional level. While many regulatory circuits governing stress… read more here.

DOI: 10.1038/s42003-020-01300-w
Abstract: Active dispersal of microorganisms is often attributed to the cells’ motile organelles. However, much less is known about whether sessile cells can access such motility through aggregation with motile counterparts. Here, we show that the… read more here.

DOI: 10.1093/nar/gky141
Abstract: Abstract High-resolution three-dimensional models of Caulobacter crescentus nucleoid structures were generated via a multi-scale modeling protocol. Models were built as a plectonemically supercoiled circular DNA and by incorporating chromosome conformation capture based data to generate… read more here.

DOI: 10.1099/mic.0.000753
Abstract: Vitamin B12 is one of the most complex biomolecules in nature. Since few organisms can synthesize B12de novo, most bacteria utilize highly sensitive and specialized transporters to scavenge B12 and its precursors. In Gram-negative bacteria,… read more here.

DOI: 10.1101/2022.01.18.476748
Abstract: Two-component systems (TCS) are often used by bacteria to rapidly assess and respond to environmental changes. The ChvG/ChvI (ChvGI) TCS conserved in α-proteobacteria is known for regulating expression of genes related to exopolysaccharide production, virulence… read more here.

Methylation‐dependent transcriptional regulation of crescentin gene (creS) by GcrA in Caulobacter crescentus
Sign Up to like & getrecommendations! Published in 2020 at "Molecular Microbiology"
DOI: 10.1111/mmi.14500
Abstract: In Caulobacter crescentus the combined action of chromosome replication and the expression of DNA methyl‐transferase CcrM at the end of S‐phase maintains a cyclic alternation between a full‐ to hemi‐methylated chromosome. This transition of the… read more here.
