Production of an extracellular matrix is a hallmark of biofilm formation. In the spore-forming bacterium Bacillus subtilis, the matrix consists of an exopolysaccharide, which is specified by the epsA-O operon, and a secreted protein TasA, which is encoded by the yqxM-sipW-tasA operon. Past and present evidence establish that the epsA-O and yqxM-sipW-tasA operons are controlled by the repressor proteins SinR and AbrB. Here, we report the identification of a novel regulatory protein Slr that promo ...[more]
