Atomic-resolution crystal structure of the Recombinant form of Scytovirin
Overview
The crystal structures of the natural and recombinant antiviral lectin, scytovirin (SVN) were solved by single-wavelength anomalous scattering and, refined with data extending to 1.3 A and 1.0 A resolution, respectively. A, molecule of SVN consists of a single chain 95 amino acids long, with an, almost perfect sequence repeat that creates two very similar domains (RMS, deviation 0.25 A for 40 pairs of Calpha atoms). The crystal structure, differs significantly from a previously published NMR structure of the, same protein, with the RMS deviations calculated separately for the N- and, C-terminal domains of 5.3 A and 3.7 A, respectively, and a very different, relationship between the two domains. In addition, the disulfide bonding, pattern of the crystal structures differs from that described in the, previously published mass spectrometry and NMR studies.
