Construction of a cell-based sensor for the detection of autoinducer-2
SPIE Proceedings, 2012Microbially Induced Corrosion (MIC) occurs at metal surfaces and is associated with microorganisms and their metabolic activities. These microbes can coexist as biofilms, growing as synergistic communities (consortia) that are able to affect electrochemical processes, both cathodic and anodic, often through co-operative metabolism.

Bacteroides species produce Vibrio harveyi autoinducer 2-related molecules
Anaerobe, 2005Quorum sensing is a density-dependent gene regulation mechanism that has been described in many bacterial species in the last decades. Bacteria that use quorum sensing as part of their gene regulation circuits produce molecules called autoinducers that accumulate in the environment and activate target genes in a quorum-dependent way.

Oxazaborolidine derivatives inducing autoinducer-2 signal transduction in Vibrio harveyi
Bioorganic & Medicinal Chemistry, 2008The bioluminescence of the marine bacterium Vibrio harveyi is controlled by quorum sensing. This effect is mediated by production, accumulation, and auto-detection of the species-specific autoinducer 1 (AI-1), autoinducer 2 (AI-2), and the V. cholerae autoinducer 1 (CAI-1). The V. harveyi AI-2 was recently identified as furanosyl borate diester.

Temporal regulation of enterohemorrhagic Escherichia coli virulence mediated by autoinducer-2
Applied Microbiology and Biotechnology, 2008The autoinducer-2 (AI-2) molecule is produced by many bacterial species, including various human gastrointestinal (GI) tract commensal bacteria, and has been proposed to be involved in interspecies communication. Because pathogens are likely to encounter AI-2 in the GI tract, we studied the effects of AI-2 on various phenotypes associated with ...

D-Galactose as an autoinducer 2 inhibitor to control the biofilm formation of periodontopathogens
Journal of Microbiology, 2016Autoinducer 2 (AI-2) is a quorum sensing molecule to which bacteria respond to regulate various phenotypes, including virulence and biofilm formation. AI-2 plays an important role in the formation of a subgingival biofilm composed mostly of Gram-negative anaerobes, by which periodontitis is initiated.

Mutational Analysis of a Nucleosidase Involved in Quorum-Sensing Autoinducer-2 Biosynthesis
Biochemistry, 20055'-Methylthioadenosine/S-adenosylhomocysteine nucleosidase (MTAN) is important in a number of cellular functions such as polyamine biosynthesis, methionine salvaging, biological methylation, and quorum sensing. The nucleosidase is found in many microbes but not in mammalian systems, thus making MTAN a broad-spectrum antimicrobial drug target. Substrate

The signalling molecule Autoinducer-2 is not internalised in Campylobacter jejuni.
Berliner und Munchener tierarztliche Wochenschrift, 2015Bacteria recognise and constantly adjust to changing situations by sensing environmental and self-produced signals. Autoinducer-2 (AI-2) is a signal molecule, found in many bacterial species and thus proposed to enable interspecies com- munication. Two classes of AI-2 receptors have been identified so far.
