Hepatitis delta virus (HDV) packaging requires prenylation of the HDV large protein (p27), as well as a direct protein-protein interaction between HDV proteins and hepatitis B virus (HBV) envelope protein domains. To investigate this interaction, we have analysed the binding capacity of baculovirus-expressed delta p24 and p27 proteins to synthetic peptides specific for the HBV envelope. Althoug...

regarding the role and importance of subsurface drainage in water table control, many studies have been made throughout the world to find out new techniques and more economical solutions, especially as related to different pipe envelope material and their installations. this research was conducted to investigate the use of rice husk, as drain envelope material, in drainage installations. in add...

The nature of the initial interaction of dengue virus with target cells and the extent to which this interaction defines tropism are unknown. Infection of some cells may involve antidengue antibody-mediated immune adherence to cells bearing immunoglobulin Fc receptors; however, this mechanism does not explain primary infection or the infection of cells without Fc receptors. We hypothesized that...

Retroviral vectors have been widely used in human gene therapy protocols. Entry into target cells is directed by the retroviral envelope protein, with receptor binding and postbinding fusion functions contributed mainly by the SU and TM subunits, respectively. We have generated mutants of the Moloney murine leukemia virus (MoMuLV) envelope protein with mutations in both the receptor binding dom...

Transport of precursor proteins across the chloroplastic envelope membranes requires the interaction of protein translocons localized in both the outer and inner envelope membranes. Analysis by blue native gel electrophoresis revealed that the translocon of the inner envelope membranes consisted of at least six proteins with molecular weights of 36, 45, 52, 60, 100 and 110 kDa, respectively. Ti...
