4.6Å Cryo-EM reconstruction of tobacco mosaic virus from images recorded at 300keV on a 4k×4k CCD camera
Clare, Daniel K. and Orlova, Elena (2010) 4.6Å Cryo-EM reconstruction of tobacco mosaic virus from images recorded at 300keV on a 4k×4k CCD camera. Journal of Structural Biology 171 (3), pp. 303-308. ISSN 1047-8477.
Tobacco mosaic virus (TMV) is a plant virus with a highly ordered organisation and has been described in three different structural states: As stacked disks without RNA (X-ray crystallography), as a helical form with RNA (X-ray fibre diffraction) and as a second distinct helical form with RNA (cryo-EM). Here we present a structural analysis of TMV as a test object to assess the quality of cryo-EM images recorded at 300 keV on a CCD camera. The 4.6 Å TMV structure obtained is consistent with the previous cryo-EM structure and confirms that there is a second helical form of TMV. The structure here also shows that with a similar number of TMV segments an equivalent resolution can be achieved with a 4k CCD camera at 300 keV.
