ESP capable of inhibiting biofilm
Esp, extracellular serine protease, is capable of inhibit the biofilm formation and nasal colonization of S. aureus. This by protelysing receptors essential for biofilm formation and prevention of eDNA exudation.

Usage:
Esp, extracellular serine protease, is capable of inhibit the biofilm formation and nasal colonization of S. aureus. This by protelysing receptors essential for biofilm formation and prevention of eDNA exudation. Thus, the biofilm degrading properties of ESP can be used in applications concerning biofilm degradation and infectious diseases caused by S.Aureus. In our project the aim was to evaulate and use ESP’s abilities to disrupt and eridicate the biofilm formation S.Aureus.
The encoding part of the BioBrick is derived from BBaK531005 , made by iGEM Grinnell 2011. The T7 promoter (BBak525998) has been inserted to control protein expession under IPTG induction. To regulate the protein expression under T7 promoter control, E.coli containing a T7 polymerase must be used, for instance BL21(DE3).
Biology:
Extracellular serine protease (Esp) is secreted by a subset of Staphylococcus epidermidis, which is a non-pathogenic bacterium in human nasal cavity and skin. Staphylococcus epidermis prevent colonization and biofilm formation of S.Aureus.One underlying mechanism for this is ESP’s ability to degrade proteins critical for the attachment of bacteria to the host; thus, changing S. aureus sessile form to planktonic form [10].
