Multiple Quorum Quenching Enzymes Are Active in the Nosocomial Pathogen Acinetobacter baumannii ATCC17978

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
Acinetobacter baumannii presents a typical luxI/luxR quorum sensing (QS) system (abaI/abaR) but the acyl-homoserine lactone (AHL) signal profile and factors controlling the production of QS signals in this species have not been determined yet.

Relay Architectures and Ecological Strategies of Quorum Sensing Effects on Microbial Interactions

open access: yesEnvironmental Microbiology, Volume 28, Issue 10, October 2026.
Quorum‐sensing activity in one population affects neighbouring populations through direct signal perception, QS‐regulated chemical effectors, or host‐ or environment‐mediated relays. Across distinct habitats, these relay architectures are associated with ecological strategies ranging from shared signal accessibility and reciprocal responsiveness to ...

Harnessing a versatile robust lactonase for biotechnological applications [PDF]

open access: yes, 2017
Extremozymes have gained considerable interest as they could meet industrial requirements. Among these, SsoPox is a hyperthermostable enzyme isolated from the archaeon Sulfolobus solfataricus1. This enzyme is a lactonase catalyzing the hydrolysis of acyl-

From Photons to Product – A Quantitative Study on Electron Fluxes in Synechocystis sp. PCC 6803 Applied for Oxygenase Catalysis

open access: yesPhysiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Using Cyanobacteria as chassis strains can harness sunlight as an energy source for biotechnology. Their phototrophic lifestyle requires balancing energy assimilation (source) with nutrient assimilation and biomass formation (sink). It is hypothesized that extra carbon and/or electron sinks can increase photosynthetic efficiency, allowing ...

Enzymes with Lactonase Activity against Fungal Quorum Molecules as Effective Antifungals

open access: yesBiomolecules
Since the growing number of fungi resistant to the fungicides used is becoming a serious threat to human health, animals, and crops, there is a need to find other effective approaches in the eco-friendly suppression of fungal growth.
