Biochem/physiol Actions

N-[(RS)-3-Hydroxybutyryl]-L-homoserine lactone is a member of N-acyl-homoserine lactone family. N-Acylhomoserine lactones (AHL) regulate gene expression in gram-negative bacteria, such as Echerichia and Salmonella, and are involved in quorum sensing, cell to cell communication among bacteria; for reviews see. Bacterial intercellular communication has become a target for the development of new anti-virulence drugs, and a research focus for the prevention of biofilm formation.

Acylhomoserine lactones, which serve as quorum-sensing signals in gram-negative bacteria, are produced by members of the LuxI family of synthases. LuxI is a Vibrio fischeri enzyme that catalyzes the synthesis of N-(3-oxohexanoyl)-L-homoserine lactone from an acyl-acyl carrier protein and S-adenosylmethionine.

Many bacteria produce and secrete proteases during host invasion and pathogenesis. Vibrio harveyi, an opportunistic pathogen of shrimp, is known to use a two-component quorum sensing (QS) mechanism for coordination of gene expression including protease secretion at high population densities.

With the increasing prevalence of antibiotic resistance, antimicrobial enzymes aimed at the disruption of bacterial cellular machinery and biofilm formation are under intense investigation. Several enzyme-based products have already been commercialized for application in the healthcare, food and biomedical industries.

Streptococcus mutans is the primary causative agent involved in dental caries in humans. Among important virulence factors of this pathogen, its ability to form and sustain a polysaccharide-encased biofilm (commonly called dental plaque) is vital not only to its survival

Quorum sensing is an example of community behavior prevalent among diverse bacterial species. The term "quorum sensing" describes the ability of a microorganism to perceive and respond to microbial population density, usually relying on the production and subsequent response to
