The Solution Structures and Interaction of SinR and SinI: Elucidating the Mechanism of Action of the Master Regulator Switch for Biofilm Formation in Bacillus subtilis


By: M. Milton*, G. Draughn n, B. Bobay n, S. Stowe n, A. Olson n, E. Feldmann n, R. Thompson*, K. Myers n ...

author keywords: Biofilms; Bacillus subtilis; Transcriptional regulation; NMR solution structure
MeSH headings : Amino Acid Sequence / genetics; Bacillus subtilis / genetics; Bacillus subtilis / ultrastructure; Bacterial Proteins / chemistry; Bacterial Proteins / genetics; Bacterial Proteins / ultrastructure; Biofilms / growth & development; DNA-Binding Proteins / chemistry; DNA-Binding Proteins / genetics; DNA-Binding Proteins / ultrastructure; Gene Expression Regulation, Bacterial / genetics; Molecular Docking Simulation; Mutation / genetics; Protein Binding / genetics; Protein Conformation
TL;DR: This work presents the first full-length structural model of tetrameric SinR using a hybrid approach combining high-resolution solution NMR, chemical crosslinking, mass spectrometry, and molecular docking, and provides an evidence-based mechanism that confirms how disruption of the SinR tetramer by SinI regulates gene expression.

2014 journal article

Chemical shift assignments and secondary structure prediction of the master biofilm regulator, SinR, from Bacillus subtilis


By: S. Stowe n, A. Olson n, R. Losick* & J. Cavanagh n

author keywords: NMR; SinR; Bacillus subtilis; Biofilm regulation
MeSH headings : Bacillus subtilis / metabolism; Bacterial Proteins / chemistry; Biofilms; Nuclear Magnetic Resonance, Biomolecular; Protein Structure, Secondary
TL;DR: The full-length backbone and side chain chemical shift values in addition to the experimentally derived secondary structure predictions are reported as the first step towards directly studying the complex interaction dynamics between SinR and SinI. (via Semantic Scholar)

2012 journal article

Evaluation of the toxicity of 2-aminoimidazole antibiofilm agents using both cellular and model organism systems


author keywords: 2-aminoimidazole; adjuvant; biofilm; Caenorhabditis elegans; toxicity; Toxicity of 2-aminoimidazole; antibiofilm agents
MeSH headings : Adjuvants, Pharmaceutic / toxicity; Animals; Anti-Bacterial Agents / pharmacology; Anti-Bacterial Agents / toxicity; Biofilms / drug effects; Caenorhabditis elegans; Cell Line; Dose-Response Relationship, Drug; Environmental Exposure; Fertility / drug effects; Humans; Imidazoles / pharmacology; Imidazoles / toxicity; Keratinocytes / metabolism; Tetrazolium Salts; Thiazoles; Toxicity Tests
TL;DR: The most effective antibiofilm compound had significant effects when used in conjunction with several standard antibiotics against resistant bacteria and was found to maintain the same low level of toxicity as when acting alone, bolstering its candidacy for further testing as an adjuvant.

2012 journal article

Identification of BfmR, a Response Regulator Involved in Biofilm Development, as a Target for a 2-Aminoimidazole-Based Antibiofilm Agent

BIOCHEMISTRY, 51(49), 9776–9778.

MeSH headings : Acinetobacter baumannii / drug effects; Acinetobacter baumannii / growth & development; Bacterial Proteins / chemistry; Bacterial Proteins / physiology; Biofilms / drug effects; Imidazoles / pharmacology; Microscopy, Confocal; Models, Molecular
TL;DR: The 2AI compound studied here represents a unique small molecule scaffold that targets bacterial response regulators and is cell permeable, while pull-down assays identified BfmR, a response regulator that is the master controller of biofilm formation, as a target for this compound.
