During viral entry, HIV surface glycoprotein gp120 binds to CD4, thereby anchoring the virus to the host cell surface. This interaction induces conformational changes within gp120 that expose CD4-induced (CD4i) epitope, the binding site for coreceptors (usually a member of the chemokine receptor family). In addition, HIV binds to heparan sulphate (HS), an abundant cell surface polysaccharide, through several domains of gp120, including CD4i. Thus, it may be possible to inhibit HIV binding to cells, using soluble molecules derived from HS. In this context, we proposed to characterise further the structural features of the CD4i/HS interaction. First, we produced and purified gp120 proteins mutated on four residues within CD4i, suspected to in...
