The appearance of bacterial biofilms involves secretion of polysaccharides and proteins that form an extracellular matrix embedding the bacteria. Proteases have also been observed, but their role has remained unclear. Smith and co-workers have now found that proteolysis can contribute to further recruitment of bacteria to Vibrio cholerae biofilms.
