Structure of the human neutrophil elastase gene.
The gene for human neutrophil elastase (NE), a powerful serine protease carried by blood neutrophils and capable of destroying most connective tissue proteins, was cloned from a genomic DNA library of a normal individual. The NE gene consists of 5 exons and 4 introns included in a single copy 4-kilobase segment of chromosome 11 at q14. The coding exons of the NE gene predict a primary translati...
متن کاملPrimary structure of human neutrophil elastase.
The complete amino acid sequence of human neutrophil elastase has been determined. The protein consists of 218 amino acid residues, contains two asparagine-linked carbohydrate side chains, and is joined together by four disulfide bonds. Comparison of the sequence to other serine proteinases indicates only moderate homology with porcine pancreatic elastase (43.0%) or neutrophil cathepsin G (37.2...
متن کاملCrystallization of human neutrophil elastase.
Human neutrophil elastase was inactivated by methoxysuccinyl-L-Ala-L-Ala-L-Pro-L-Ala-chloromethane. The modified enzyme was crystallized from 40 mM ammonium phosphate, pH 7.0 in the hexagonal space group P6(3) with unit cell parameters a = 74.53 A, b = 74.53 A, c = 70.88 A, alpha = beta = 90 degrees, gamma = 120 degrees. These crystals were resistant to radiation damage and diffracted beyond 1....
متن کاملTranscriptional and posttranscriptional modulation of human neutrophil elastase gene expression.
Human neutrophil elastase (NE), a 29-Kd potent serine protease stored in azurophilic granules of mature neutrophils, is coded for by the NE gene, a single copy gene with 5 exons spanning a 6-kb segment of chromosome 11 at q14. With the knowledge that the NE gene expression is limited to early myeloid cell differentiation, mechanisms modulating expression of the NE gene were evaluated in the HL-...
متن کاملMolecular screening of the neutrophil elastase gene in congenital neutropenia.
Congenital neutropenia is a rare hematopoietic disease, which occurs sporadically or as an auto-somal dominant inherited disorder. Pathogenesis of congenital neutropenia can now be attributed to mutations of the ELA2 gene encoding neutrophil elastase. A child with severe congenital neutropenia with a heterozygous mutation G1887A in exon 2 of ELA2 gene is reported.
