Chronic hepatitis B virus (HBV) infection is a major cause of liver disease. Only interferon-alpha and the nucleosidic inhibitors of the viral polymerase, 3TC and adefovir, are approved for therapy. However, these therapies are limited by the side effects of interferon and the substantial resistance of the virus to nucleosidic inhibitors. Potent new(More)
A novel class of antibiotic acyldepsipeptides (designated ADEPs) exerts its unique antibacterial activity by targeting the peptidase caseinolytic protease P (ClpP). ClpP forms proteolytic complexes with heat shock proteins (Hsp100) that select and process substrate proteins for ClpP-mediated degradation. Here, we analyse the molecular mechanism of ADEP(More)
The genetic diversity of human immunodeficiency virus (HIV) is a major concern thought to impact on immunologic escape and eventual vaccine efficacy. Here, simple and rapid methods are described for the detection and estimation of genetic divergence between HIV strains on the basis of the observation that DNA heteroduplexes formed between related sequences(More)
The active form of HIV-1 reverse transcriptase (RT) is a p66/p51 heterodimer, in which the p51 subunit is generated by C-terminal proteolytic cleavage of p66. A well-known problem of p66 recombinant expression is partial cleavage of a 15-kDa peptide from the C-terminus by host proteases that can not be completely suppressed. In order to analyse the(More)
It has been suggested that the human immunodeficiency virus type 2 (HIV-2) and the simian immunodeficiency virus from rhesus macaques (SIVmac) evolved from the sooty mangabey virus SIVsm (ref. 1). We now describe an HIV-2-related isolate, HIV-2-D205, from a healthy Ghanaian woman that is genetically equidistant to the prototypic HIV-2 strains and to SIVsm(More)
