The envelope glycoprotein (gp70) of a molecularly cloned, replication-defective feline leukemia virus (FeLV-FAIDS clone 61C) carries determinants for induction of fatal immunodeficiency disease, whereas the gp70 of its companion replication-competent, probably parent virus (clone 61E) does not. Immunoprecipitation analysis of the extracellular glycoproteins of 61E and EECC, a replication-compet...
Infection of human cells by human T cell leukemia virus type 1 (HTLV-1) is mediated by the viral envelope glycoproteins. The gp46 surface glycoprotein binds to cell surface receptors, including heparan sulfate proteoglycans, neuropilin 1, and glucose transporter 1, allowing the transmembrane glycoprotein to initiate fusion of the viral and cellular membranes. The envelope glycoproteins are reco...
Epizootic strains of Venezuelan equine encephalitis virus (VEEV) cause epidemics by exploiting equines as highly efficient amplification hosts for mosquito transmission. Although phylogenetic studies indicate that epizootic VEEV strains emerge via mutation from enzootic progenitors that are incapable of efficient equine amplification, the molecular mechanism(s) involved remain enigmatic. The co...
Biological systems provide many examples of specifically tailored, nanostructured molecules with highly optimized properties and characteristics. These biomaterials are composite materials and consist of an inorganic component and a special organic matrix. Crystalline bacterial cell surface layers (S-layers( are the outermost cell envelope component of many eubacteria and archaea and are compos...
The two HCV envelope glycoproteins E1 and E2 are released from HCV polyprotein by signal peptidase cleavages. These glycoproteins are type I transmembrane proteins with a highly glycosylated N-terminal ectodomain and a C-terminal hydrophobic anchor. After their synthesis, HCV glycoproteins E1 and E2 associate as a noncovalent heterodimer. The transmembrane domains of HCV envelope glycoproteins ...
Mucosal transmission of the human immunodeficiency virus (HIV) results in a bottleneck in viral genetic diversity. Gnanakaran and colleagues used a computational strategy to identify signature amino acids at particular positions in Envelope that were associated either with transmitted sequences sampled very early in infection, or sequences sampled during chronic infection. Among the strongest s...
Human immunodeficiency virus type 1 (HIV-1) entry into target cells involves sequential binding of the gp120 exterior envelope glycoprotein to CD4 and to specific chemokine receptors. Soluble CD4 (sCD4) is thought to mimic membrane-anchored CD4, and its binding alters the conformation of the HIV-1 envelope glycoproteins. Two cross-competing monoclonal antibodies, 17b and CG10, that recognize CD...
