Crystal Structure of Elastase

Caption: This drawing represents the crystal structure of the NSP neutrophil elastase, shown in blue, bound to the Staphylococcus aureus Eap protein, EapH1, shown in gold. Two Kansas State University biochemists have discovered that S. aureus secretes a family of proteins that prevent neutrophil serine proteases, or NSPs, from functioning -- an important finding for understanding how infections are established.
