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

Environmental bacteria from Hawai'i and the Bahamas were analyzed for N-acyl homoserine lactone-based quorum sensing systems. The dataset includes findings from two newly described Pseudomonadota species and two Gram-positive Actinomycetota strains. It was created by Christy R. Handel and last updated on May 8, 2026.

Use Cases

• Comparative genomic analysis of luxI/R homologs based on the described hidden Markov model (HMM) searches.
• Phylogenetic study of LuxR-family protein domain architecture divergence mentioned in the description.
• Investigating the association of solitary luxI genes with metabolic and redox processes in Actinomycetota.
• Validating AHL production via LC-MRM-MS methods as described for the studied bacterial strains.

Strengths

• Data is associated with a specific research study investigating AHL-QS in underexplored lineages.
• Includes analysis from four distinct bacterial strains from specific environmental sources.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• The dataset is small at 84.1 KB, indicating limited scope.
• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
