Purification, crystallization and preliminary X-ray diffraction analysis of the Staphylococcus epidermidis extracellular serine protease Esp.

ABSTRACT: Esp, an extracellular serine protease from Staphylococcus epidermidis, has been shown to inhibit S. aureus biofilm formation and nasal colonization. The full-length 27?kDa pro-Esp was purified and digested with thermolysin to obtain mature Esp. The mature Esp containing 216 residues crystallized in space group P2(1), with unit-cell parameters a = 39.5, b = 61.2, c = 42.5?Å, ? = 98.2° and one molecule in the asymmetric unit, with an estimated solvent content of 42%. A diffraction data set has been collected to 1.8?Å resolution on a rotating-anode home-source facility.
