We report the 2.7 A resolution structure of a chimeric rhinovirus, MN-III-2, that displays part of the HIV-1 gp120 V3 loop and elicits HIV-neutralizing antibodies. The V3 loop insert is dominated by two type I β turns. The structures of two adjacent tripeptides resemble those of analogous segments in three Fab/V3 loop peptide complexes. Although two of the three corresponding antibodies bind and neutralize...

Polioviruses are icosahedral single-standed RNA viruses, which belong to the picornavirus family, and occur as three distinct serotypes. All three serotypes of poliovirus can infect primates, but only type 2 can infect mice. The crystal structures of a type 1 and a type 3 poliovirus are already known. Structural...
