Description
Purified recombinant HIV1 vif IIIB protein
HIV-1 is composed of two copies of single-stranded RNA enclosed by a conical capsid comprising the viral protein p24, typical of lentiviruses. As a component of the HIV-virus particle there are approximately 2000 molecules per virus particle, or at a molecule weight of 24 kDa, about 10^4 virus particles per picogram of p24. HIV gag (group-specific antigen) : codes for the Gag polyprotein, which is processed during maturation to MA (matrix protein, p17); CA (capsid protein, p24); SP1 (spacer peptide 1, p2); NC (nucleocapsid protein, p7); SP2 (spacer peptide 2, p1) and p6
