C-Terminal Propeptide of BKA has a Protease Sensitive Structure Without any Inhibitory Effect on BKA
In our previous study, we compared the two α-amylase enzymes from Bacillus sp.KR8104, BKA∆(N44) and BKA∆(N44C193) which is the secreted form of it. The results indicated that the presence of 193 amino acids propeptide in the C-terminal of BKA∆(N44) changed its enzymatic parameters like an uncompetitive inhibitor in comparison to BKA∆(N44C193). In the present study, we cloned the DNA sequence of...

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 ...

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...
The Caldariomyces fumago chloroperoxidase (CPO) is synthesised as a 372-aa precursor which undergoes two proteolytic processing events: removal of a 21-aa N-terminal signal peptide and of a 52-aa C-terminal propeptide. The Aspergillus niger expression system developed for CPO was used to get insight into the function of this C-terminal propeptide. A. niger transformants expressing a CPO protein...
GDF-8 is a negative regulator of skeletal muscle mass. The mechanisms which regulate the biological activity of GDF-8 have not yet been elucidated. Analogous to the TGF-beta system, GDF-8 propeptide binds to and inhibits the activity of GDF-8. In these studies, we define the critical domain of the GDF-8 propeptide necessary for inhibitory activity. Two molecules of GDF-8 propeptide monomer inhi...
Pyrolysin-like proteases from hyperthermophiles are characterized by large insertions and long C-terminal extensions (CTEs). However, little is known about the roles of these extra structural elements or the maturation of these enzymes. Here, the recombinant proform of Pyrococcus furiosus pyrolysin (Pls) and several N- and C-terminal deletion mutants were successfully expressed in Escherichia c...
Prohormone convertase 1 (PC1) is a serine proteinase responsible for the proteolytic processing of many precursor proteins within the regulated secretory pathway. The activity of PC1 is potentially regulated by two endogenous inhibitors, the PC1 propeptide and proSAAS. Here we have investigated the effect of proSAAS and propeptide-containing constructs on PC1 carboxy-terminal processing and act...
We report on the diagnostic validity of the serum concentrations of the C-terminal propeptide of type I procollagen (a marker of bone formation) and of the urinary excretion of deoxypyridinoline (a marker of bone resorption) in a consecutive series of 89 tumour patients who were routinely examined by 99mTc-methylene bisphosphonate bone scintigraphy for detection of bone metastases. Z score anal...
