N-acyl-homoserine Lactone Quorum Sensing Data from Underexplored Bacterial Lineages

Environmental Bacteria from Hawai'i and the Bahamas were investigated for N-acyl homoserine lactone-based quorum sensing systems. The dataset, authored by Christy R. Handel and last updated in April 2026, likely contains results from genomic analyses and mass spectrometry for four bacterial strains, including two newly described species. It expands the known diversity of bacterial signaling systems beyond the canonical Pseudomonadota model.

Use Cases

• Comparative genomics of luxI/R homologs based on the described phylogenetic analyses.
• Analyzing the genomic context of signaling genes linked to metabolism and redox processes as mentioned in the description.
• Studying the domain architecture of LuxR-family proteins based on the described helix-turn-helix regulatory features.
• Investigating AHL production in Gram-positive Actinomycetota based on the LC-MRM-MS results described.

Strengths

• Data is derived from custom hidden Markov models and liquid chromatography-multiple reaction monitoring-mass spectrometry (LC-MRM-MS) as described.
• Includes results from targeted gene disruption experiments in Rhodococcus kroppenstedtii Y88A.
• Published under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (157.0 KB), indicating limited scope.
