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

A 311.5 KB Excel file by Christy R. Handel, last updated in April 2026, presents findings on N-acyl-homoserine lactone-based quorum sensing in non-canonical bacterial lineages. The data likely contains results from custom hidden Markov model analyses, genomic context studies, and liquid chromatography-mass spectrometry used to investigate AHL production in environmental bacteria from Hawai'i and the Bahamas.

Use Cases

• Comparative genomics of luxI/R homologs based on phylogenetic analyses mentioned in the description
• Modeling non-canonical AHL-QS regulatory architectures based on described LuxR domain structures
• Analyzing associations between luxI genes and metabolic/redox processes in Actinomycetota as described
• Validating AHL production via mass spectrometry data likely contained in the dataset

Strengths

• Data is derived from custom hidden Markov models and liquid chromatography-multiple reaction monitoring-mass spectrometry (LC-MRM-MS) as described
• Includes analysis of bacteria from specific underexplored environments: a taro lo'i and lava cave in Hawai'i and a hypersaline mat in the Bahamas
• Released under a permissive CC-BY-4.0 license for reuse
• File size of 311.5 KB suggests a focused, manageable dataset

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset's small size (311.5 KB) indicates limited scope, likely containing summary or key results rather than raw sequencing data
