CH is an autosomal dominant disease in which blood-cell production from the bone marrow oscillates with 21-day periodicity. Circulating neutrophils vary between almost normal numbers and zero. During intervals of neutropenia, affected individuals are at risk for opportunistic infection. Monocytes, platelets, lymphocytes and reticulocytes also cycle with the same frequency.<ref>PMID:14673143</ref> <ref>PMID:10581030</ref> Defects in ELANE are the cause of neutropenia severe congenital autosomal dominant type 1 (SCN1) [MIM:[https://omim.org/entry/202700 202700]. SCN1 is a disorder of hematopoiesis characterized by a maturation arrest of granulopoiesis at the level of promyelocytes with peripheral blood absolute neutrophil counts below 0.5 x 10(9)/l and early onset of severe bacterial infections.<ref>PMID:20220065</ref> | ||

| + | 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. | ||
