N-acyl-homoserine Lactone Quorum Sensing Data in Actinomycetota and Pseudomonadota

A 10.0 KB document by Christy R. Handel, last updated in April 2026, investigates N-acyl homoserine lactone-based quorum sensing in underexplored bacterial lineages. The research uses custom hidden Markov models and LC-MRM-MS to analyze AHL production in environmental strains from Hawai'i and the Bahamas. Findings suggest AHL signaling in Actinomycetota may operate through regulatory frameworks distinct from classical systems.

Use Cases

• Comparative genomic analysis of luxI/R homologs based on the described phylogenetic and domain architecture findings.
• Studying the ecological role of AHL signaling in non-canonical bacterial lineages based on the environmental sample sources.
• Developing new hidden Markov models for gene identification based on the methodology described.
• Investigating the link between AHL production and metabolic/redox processes in Actinomycetota based on the genomic context analysis.

Strengths

• Data is associated with a specific, peer-reviewed research investigation into quorum sensing.
• The dataset is openly available under a CC-BY-4.0 license.
• Includes analysis of bacterial strains from distinct, underexplored environments like lava caves and hypersaline mats.

Limitations

• The dataset is a 10.0 KB DOCX file, indicating a very limited scope, likely a summary document rather than raw data.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The description does not specify the exact data format or provide sample records for immediate analysis.
