GroovDB

GroovDB catalogs curated ligand-inducible prokaryotic transcription factors with associated biosensor sequences, ligands, and operator data to support design and analysis of chemically responsive genetic circuits.

Key Features:

• Curated Data: Entries include biosensor sequences, associated ligands, and operator data relevant for engineering chemically responsive genetic circuits.
• Verified Interactions: Ligand–DNA interaction data are verified against primary literature to ensure accuracy of reported biosensor–ligand and biosensor–operator relationships.
• Automated Curation Pipeline: A programmatic pipeline fetches metadata, structural information, and literature references for each entry.
• Visualization Tool: A custom visualization of natural genetic context displays surrounding genes and operon organization to inform potential alternative ligands and regulatory context.

Scientific Applications:

• High-throughput Screening: Provides characterized transcription factors and ligand annotations to support screening of biosensor candidates.
• Dynamic Feedback Regulation: Enables selection of ligand-inducible regulators for designing circuits with ligand-responsive feedback control.
• Multilayer Logic Gates: Supplies data on multiple ligand-inducible transcription factors and operators for constructing combinatorial and multilayer genetic logic gates.
• Diagnostic Applications: Supports development of ligand-responsive diagnostic elements by providing ligand annotations and characterized biosensor sequences.

Methodology:

Programmatic pipeline fetches metadata, structural information, and references for each entry, and ligand–DNA interaction data are verified against the literature.
