Part of a computer generated map showing the electron density (green) for the protein alpha- monocharin. Also shown (in white, blue and red) is the atomic structural model. Alpha-monocharin is a member of the ribosome-inactivity protein family. These plant proteins are thought to have a role in blocking the transmission of viruses. While plants rich in them have long been used in traditional Chinese medicines, the anti-viral and anti-tumour potential of these proteins is now attracting increasing interest in scientific circles. The structure was determined using X-ray diffraction crystallography to a resolution of 2 angstroms.
