Purification, crystallization and preliminary X‐ray diffraction analysis of the
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 P21, with unit‐cell parameters a = 39.5, b = 61.2, c = 42.5 Å, β = 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.
