VicRK (WalRK or YycFG) is a conserved 2-component regulatory system (TCS) that regulates cell division, cell wall biosynthesis, and homeostasis in low-GC Gram-positive bacteria. VicRK is also associated with biofilm formation of Streptococcus mutans

Streptococcus mutans, a major acidogenic component of the dental plaque biofilm, has a key role in caries etiology. Previously, we demonstrated that the VicRK two-component signal transduction system modulates biofilm formation, oxidative stress and

Two-component systems (TCSs) are ubiquitous among bacteria and are among the most elegant and effective sensing systems in nature. They allow for efficient adaptive responses to rapidly changing environmental conditions. In this study, we investigate

Two-component systems (TCSs) are important for the adaptation and survival of bacteria and fungi under stress conditions. A TCS is often composed of a membrane-bound sensor histidine kinase (SK) and a response regulator (RR), which are relayed throug

Summary Streptococcus mutans is recognized as one of the key contributors to the dysbiotic state that results in dental caries. While existing treatment strategies reduce the incidence of tooth decay, they also eliminate both the cariogenic and benef

We have previously characterized the interactions of the response regulator ComE from Streptococcus mutans and DNA binding sites through DNase I footprinting and electrophoretic mobility shift assay analysis. Since response regulator functions are of

Bacteria that cause chronic and/or recurrent diseases often rely on a biofilm lifestyle. The foundation of the biofilm structure is the extracellular polymeric substance (EPS) that acts as a barrier to both effectors of the immune system and antimicr

Gene synthesis is a convenient tool that is widely used to make genes for a variety of purposes. All current protocols essentially take inside-out approaches to assemble complete genes using DNA oligonucleotides or intermediate fragments. Here we pre

The ciaRH operon in Streptococcus mutans contains 3 contiguous genes, ciaXRH . Unlike the CiaRH system in other streptococci, only the ciaH -null mutant displays defective phenotypes, while the ciaR -null mutant behaves like the wild type. The object
