A ubiquitous host endoprotease(s) responsible for activation of the fusion glycoprotein precursor (F0) of virulent Newcastle disease virus (NDV) is an important determinant for its spreading and organ tropism in the host. To characterize the virus-activating protease (VAP), we isolated endoprotease activity from the trans Golgi membranes of rat liver cells(More)
Intracellular proteolytic processing of fusion glycoprotein precursors (F0) of paramyxoviruses, i.e. a virulent strain of Newcastle disease virus (NDV), parainfluenza virus type 3 (PIV3) and simian virus 5 (SV5), was examined in NALM6 and BSC40 cells and compared with that in LLCMK2 cells to investigate the distribution of the virus-activating protease(s)(More)
DsbC, which catalyzes disulfide isomerization, was overproduced in the periplasm of Escherichia coli and purified from the periplasmic fraction by osmotic shock and anion-exchange chromatography. The active site of the purified DsbC was found to be an oxidized form (ox-DsbC) which could be converted to the reduced form (red-DsbC) by the addition of(More)
