SinR transcription factor
SinR protein is the master regulator of biofilm formation in Bacillus subtillis. In the active state, it represses biofilms. The regulatory pathway in which SinR lies is displayed in Figure 1. SinI inhibits the action of SinR by disrupting its' ability to bind DNA. The downstream regulatory network contains the exopolysaccharide (eps) and yqxM (containing an EPS bridging protein TasA) operons.

Usage and Biology
The gene is 333bp long and can be seen clearly on a gel when cloned from B. subtilis:
