Divalent cation sites in tomato bushy stunt virus. Difference maps at 2-9 A resolution.
نویسندگان
چکیده
Difference electron density maps, using as few as four 1/2 degrees oscillation photographs, have been computed for tomato bushy stunt virus crystals soaked in EDTA. GdCl3 and silicotungstate. The maps define a double divalent cation site, responsible for regulating expansion of the virus particle, as well as sites for binding tungstate anions.

Calcium binding sites in tomato bushy stunt virus visualized by Laue crystallography.
We have collected Laue diffraction data from crystals of tomato bushy stunt virus using the full white X-ray spectrum from the wiggler magnet of the Synchrotron Radiation Source at Daresbury, U.K. A single 24 second exposure of a crystal soaked in EDTA yielded a data set that was 90% complete between 6 and 3.5 A resolution. A large proportion of the data could be measured using an overlap decon...
متن کاملStructure of Tomato Bushy Stunt Virus V.t Coat Protein Sequence Determination and its Structural Implications
CVe report the chemically determined sequence of most of the polypeptide chain of the coat protein of tomato bushy stunt virus. Peptide locations have been determined by comparison with the high-resolution electron density map from X-ray crystallographic analysis as well as by conventional chemical overlaps. Three small gaps remain in the 387-residue sequence. Positively charged sidechains are ...

متن کاملTomato bushy stunt virus (TBSV) infecting Lycopersicon esculentum.
Tomato bushy stunt virus (TBSV) was detected in tomato crop (Lycopersicon esculentum) in Egypt with characteristic mosaic leaf deformation, stunting, and bushy growth symptoms. TBSV infection was confirmed serologically by ELISA and calculated incidence was 25.5%. Basic physicochemical properties of a purified TBSV Egh isolate were identical to known properties of tombusviruses of isometric 30-...
متن کاملEnhanced competitiveness of tomato bushy stunt virus defective interfering RNAs by segment duplication or nucleotide insertion.
We have analyzed atypical tomato bushy stunt virus defective interfering (DI) RNA species which accumulated during a passage series in protoplasts. We present a rationale for the order of appearance of these molecules and show, using competition assays, that either segment duplication or single nucleotide insertion can enhance DI RNA competitiveness. Possible mechanisms for the introduction of ...
