Antimicrobial Peptides: A Promising Alternative to Conventional Antimicrobials for Combating Polymicrobial Biofilms

Advanced Science, Volume 12, Issue 1, January 9, 2025.
Antimicrobial peptides (AMPs) are promising alternatives to conventional treatments for polymicrobial biofilms, which increase pathogen resistance. AMPs disrupt biofilm extracellular matrices and microbial membranes, inhibiting biofilm formation and enhancing antibiotic efficacy. Current research addresses challenges like stability and production costs

CerM and Its Antagonist CerN Are New Components of the Quorum Sensing System in Cereibacter sphaeroides, Signaling to the CckA/ChpT/CtrA System

MicrobiologyOpen, Volume 13, Issue 6, December 2024.
The quorum sensing (QS) system of Cereibacter sphaeroides includes six LuxR homologs and one acylhomoserine lactone synthase homolog. Two LuxR homologs, CerM and CerN, are involved in regulating the expression of ctrA, which is part of the CckA/ChpT/CtrA two‐component system that controls flagellar motility.

Onion‐pathogenic Burkholderia species: Role and regulation of characterized virulence determinants

Plant Pathology, Volume 73, Issue 9, Page 2281-2297, December 2024.
Protein secretion systems and toxoflavin are well‐characterized virulence factors in onion‐pathogenic Burkholderia species. The tofIMR quorum‐sensing system and qsmR regulate multiple Burkholderia virulence factors. Abstract Members of the bacterial genus Burkholderia are a routine threat to onion production worldwide.

Acyl-homoserine lactone-based quorum sensing in the Roseobacter clade: complex cell-to-cell communication controls multiple physiologies [PDF]

, 2013
Bacteria have been widely reported to use quorum sensing (QS) systems, which employ small diffusible metabolites to coordinate gene expression in a population density dependent manner. In Proteobacteria, the most commonly described QS signaling molecules

Engineered Cell Elongation Promotes Extracellular Electron Transfer of Shewanella Oneidensis

Advanced Science, Volume 11, Issue 41, November 6, 2024.
This work investigates how cell elongation impacts the extracellular electron transfer of Shewanella oneidensis MR‐1 via genetic engineering to inhibit divisome formation. The electrophysiology of cell elongation is systematically elucidated in terms of intracellular generation, trans‐membrane transfer, and biofilm formation.

Phosphonoalamides Reveal the Biosynthetic Origin of Phosphonoalanine Natural Products and a Convergent Pathway for Their Diversification

Angewandte Chemie, Volume 136, Issue 32, August 5, 2024.
The Streptomyces phosphonoalamides result from the convergence of phosphonoalanine (PnAla) biosynthesis and peptide ligation pathways. The transamination of phosphonopyruvate (PnPy) to PnAla drives unfavorable C−P bond formation despite its reversibility, establishing this early branch of phosphonate biosynthesis, while the promiscuity of the dipeptide
