== Publication Abstract from PubMed ==
 +
The mechanism of action of a general class of mechanism-based inhibitors of serine proteases, including human neutrophil elastase (HNE), has been elucidated by determining the X-ray crystal structure of an enzyme-inhibitor complex. The captured intermediate indicates that processing of inhibitor by the enzyme generates an N-sulfonyl imine functionality that is tethered to Ser195, in accordance with the postulated mechanism of action of this class of inhibitors. The identity of the HNE-N-sulfonyl imine species was further corroborated using electrospray ionization mass spectrometry.
