We have previously shown that the 15-amino acid carboxyl-terminal propeptide of probarley lectin is necessary for the proper sorting of this protein to the plant vacuole. A mutant form of the protein lacking the carboxyl-terminal propeptide is secreted. To test whether the carboxyl-terminal propeptide is the vacuole sorting determinant of probarley lectin, we examined in transgenic tobacco the ...
Moritella viscosa causes winter ulcer disease in salmonids. The aim of the present work was to isolate and partially characterise an extracellular peptidase from M. viscosa, and to study its role in virulence. The peptidase, termed MvP1, was a 38-kDa metallopeptidase produced in late exponential growth. The optimum temperature for MvP1 was 40 degrees C, but the enzyme was active over a broad ra...
Abbreviations: ZP, zona pellucida; ZPG, ZP glycoprotein; VE, vitelline envelope; VEG, VE glycoprotein; mZP, mouse ZP; hZP, human ZP; SS, signal sequence; CTP, C-terminal propeptide; CFCS, consensus furin cleavage-site; TMD, transmembrane domain; ZPD, ZP domain; NTS, N-terminal subdomain; CTS, C-terminal subdomain; EHP, external hydrophobic patch; IHP, internal hydrophobic patch; CP, charged pat...
Fibrillin microfibrils are 10-12 nm diameter, extracellular matrix assemblies that provide dynamic tissues of metazoan species with many of their biomechanical properties as well as sequestering growth factors and cytokines. Assembly of fibrillin monomers into microfibrils is thought to occur at the cell surface, with initial steps including proprotein processing, multimerization driven by the ...
The folding and assembly of procollagen occurs within the cell through a series of discrete steps leading to the formation of a stable trimer consisting of three distinct domains: the N-propeptide, the C-propeptide and the collagen triple helix flanked at either end by short telopeptides. We have established a semi-permeabilized cell system which allows us to study the initial stages in the fol...
Myostatin is a transforming growth factor-beta family member that acts as a negative regulator of skeletal muscle mass. To identify possible myostatin inhibitors that may have applications for promoting muscle growth, we investigated the regulation of myostatin signaling. Myostatin protein purified from mammalian cells consisted of a noncovalently held complex of the N-terminal propeptide and a...
von Willebrand factor (vWF) is a multimeric adhesive glycoprotein with one factor VIII binding site/subunit. Prior reports suggest that posttranslational modifications of vWF, including formation of N-terminal intersubunit disulfide bonds and subsequent cleavage of the propeptide, influence availability and/or affinity of factor VIII binding sites. We found that deletion of the vWF propeptide p...
We report pediatric age- and sex-specific 95% reference intervals for procollagen type I C-terminal propeptide (PICP), the cross-linked C-terminal telopeptide of type I collagen (ICTP), and procollagen type III N-terminal propeptide (P3NP), measured in plasma from 302 schoolchildren (156 boys, 146 girls) ages 4-19 years. All three markers displayed a significant variation with age (ANOVA P < or...
The Galanthus nivalis agglutinin (GNA) is synthesized as a preproprotein. To corroborate the role of the different targeting peptides in the topogenesis of GNA and related proteins, different constructs were made whereby both the complete original GNA gene and different truncated sequences were coupled to the enhanced green fluorescent protein (EGFP). In addition, a GNA ortholog from rice that ...
We examined the ability of Aeromonas hydrophila to lyse elastin. Eight of 13 strains showed elastolytic activity on agar medium containing elastin and 5 strains did not. In order to examine the involvement of the metalloprotease of A. hydrophila (AMP) in elastolytic activity, we made the amp-deletion mutant strain from an elastolytic strain. The elastolytic activity of the strain decreased with...
