Abstract

Summary

The molecular weights of the protein subunits of ringspot virus, belladonna mottle virus and brome mosaic virus were estimated by the equilibrium centrifugation method of Yphantis to be 17,300, 20,700 and 17,200, respectively.

Solutions of the virus protein subunit monomers were prepared by suspending the virus particles in neutral buffers containing 6-urea and Cleland's reagent; preliminary tests with well-characterized proteins showed that the urea solution decreased the partial specific volume of the proteins by about 0.02 to 0.03 g./ml.

In solvents without urea brome mosaic virus dimer subunits had a molecular weight of about 40,000.
