The hiuABC operon mediates xenosiderophore utilization in Caulobacter crescentus [PDF]
Journal of BacteriologyCaulobacter species are common residents of soil and aquatic ecosystems, where bioavailable iron is often extremely limited. Like other diderm bacteria, Caulobacter crescentus can acquire Fe(III) via outer-membrane TonB-dependent transporters (TBDTs ...

In situ architecture of the Tad pilus machine in Caulobacter crescentus [PDF]
mBioThe tight adherence (Tad) pilus is a broadly distributed and evolutionarily distinct subclass of type IV pili that mediate cell adhesion, biofilm formation, predation, and surface sensing in many bacteria, including Caulobacter crescentus, Myxococcus ...

Stalk formation of Brevundimonas and how it compares to Caulobacter crescentus
PLoS ONE, 2017 The Caulobacter crescentus cell extension known as a stalk represents an unusual bacterial morphology. C. crescentus produces stalks under multiple nutrient conditions, but the length of the stalk is increased in response to phosphate starvation. However,

Deficiency in peptidoglycan recycling promotes β-lactam sensitivity in Caulobacter crescentus [PDF]
mBioPeptidoglycan (PG)-modifying enzymes play a crucial role in cell wall remodeling, essential for growth and division. Cell wall degradation products are transported to the cytoplasm and recycled back in most gram-negative bacteria, and PG recycling is ...

Chromosome organization shapes replisome dynamics in Caulobacter crescentus [PDF]
Nature CommunicationsDNA replication in bacteria takes place on highly compacted chromosomes, where segregation, transcription, and repair must occur simultaneously. Within this dynamic environment, colocalization of sister replisomes has been observed in many bacterial ...

Control of a gene transfer agent cluster in Caulobacter crescentus by transcriptional activation and anti-termination [PDF]
Nature CommunicationsGene Transfer Agents (GTAs) are phage-like particles that cannot self-multiply and be infectious. Caulobacter crescentus, a bacterium best known as a model organism to study bacterial cell biology and cell cycle regulation, has recently been demonstrated

Upstream CtrA-binding sites both induce and repress pilin gene expression in Caulobacter crescentus [PDF]
BMC GenomicsPili are bacterial surface structures important for surface adhesion. In the alphaproteobacterium Caulobacter crescentus, the global regulator CtrA activates transcription of roughly 100 genes, including pilA which codes for the pilin monomer that makes ...
