摘要：

Tobacco mosaic virus coat protein forms 2 helical aggregates, with 161/3 and 17 1/3 subunits/turn. Both were studied and compared with the intact virus by recording X-ray diffraction from oriented gels and calculating difference Fourier maps. The protein forms have structures similar to each other and to the protein part of the virus, even in the low radius region, which has a different structure in the crystalline disk form of the protein. The RNA is replaced in the helical protein forms by at least 1 bound anion. The difference between the protein forms may possibly be related to the conformation of 1 or more of the arginine groups that bind RNA in the intact virus.
