AI Article Synopsis

  • The genome of caulobacter phage phiCb5 has been fully sequenced, identifying four key open reading frames (ORFs) related to its function.
  • Unlike other phages in the Leviviridae family, phiCb5's lysis protein gene overlaps with the replicase gene, and its lysis protein is approximately twice as long as that of the MS2 phage, potentially featuring two transmembrane helices.
  • The analysis also showed a stable 5' stem-loop structure in the genome and a notably shorter 3' untranslated region (UTR) with just three stem-loops.

Article Abstract

The complete genome sequence of caulobacter phage phiCb5 has been determined, and four open reading frames (ORFs) have been identified and characterized. As for related phages, the ORFs code for maturation, coat, replicase, and lysis proteins, but unlike other Leviviridae members, the lysis protein gene of phiCb5 entirely overlaps with the replicase in a different reading frame. The lysis protein of phiCb5 is about two times longer than that of the distantly related MS2 phage and presumably contains two transmembrane helices. Analysis of the proposed genome secondary structure revealed a stable 5' stem-loop, similar to other phages, and a substantially shorter 3' untranslated region (UTR) structure with only three stem-loops.

To explore how microbial interactions within the rhizosphere influence the diversity and functional roles of bacterial communities, we isolated 21 bacterial strains from soil samples collected near Rocky Branch Creek on the University of South Carolina campus. Our findings revealed that a significant proportion of the isolated bacterial strains are lysogenic. Contrary to predictions of a narrow host range, most of the bacteriophages derived from these lysogenic bacteria demonstrated the ability to infect a broad range of bacterial strains.

Upstream CtrA-binding sites both induce and repress pilin gene expression in Caulobacter crescentus.

Pili 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 up the pilus filament. While most CtrA-activated promoters have a single CtrA-binding site at the - 35 position and are induced at the early to mid-predivisional cell stage, the pilA promoter has 3 additional upstream CtrA-binding sites and it is induced at the late predivisional cell stage.

Gene 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 to produce bona fide GTA particles (CcGTA). Since C.

Structural mechanisms of Tad pilus assembly and its interaction with an RNA virus.

Sci Adv

Center for Phage Technology, Department of Biochemistry and Biophysics, Texas A&M University, College Station, TX 77843, USA.

Tad (tight adherence) pili, part of the type IV pili family, are crucial for mechanosensing, surface adherence, bacteriophage (phage) adsorption, and cell-cycle regulation. Unlike other type IV pilins, Tad pilins lack the typical globular β sheet domain responsible for pilus assembly and phage binding. The mechanisms of Tad pilus assembly and its interaction with phage ΦCb5 have been elusive.

Previous studies have identified diverse bacteriophages that infect strain CB15 ranging from small RNA phages to four genera of jumbo phages. In this study, we focus on 20 bacteriophages whose genomes range from 40 to 60 kb in length. Genome comparisons indicated that these diverse phages represent six phage genera and one additional genus that includes both and phages.
