Whereas gp120 CD4-induced structures have been largely documented and at least in part elucidated by crystallization, information about gp120 coreceptor-induced structures remains incomplete despite numerous studies. In this work, mutations were carried out in a selected internal region of HIV-1/YU2 gp120, proximal to the CD4-binding site, because of its(More)
The three-dimensional structure of CD4M33, a mimic of the host-cell receptor-antigen CD4 and a powerful inhibitor of CD4-gp120 (viral envelope glycoprotein 120) interaction and HIV-1 entry into cells [Martin, Stricher, Misse, Sironi, Pugniere, Barthe, Prado-Gotor, Freulon, Magne, Roumestand et al. (2003) Nat. Biotechnol. 21, 71-76], was solved by 1H-NMR and(More)
