X射线衍射研究表明，南方菜豆花叶病毒蛋白亚基的多肽链具有与番茄丛矮病毒壳结构域非常相似的折叠。南方菜豆花叶病毒缺乏番茄丛矮病毒的突起结构域。在这些病毒中观察到的三级结构可能特别适合于在含有RNA的小的球形植物病毒中形成蛋白质外壳。
X-ray diffraction studies reveal that the polypeptide chain of the southern bean mosaic virus protein subunit has a fold closely similar to the shell domain of tomato bushy stunt virus. The protruding domain of tomato bushy stunt virus is absent in southern bean mosaic virus. The tertiary structure observed in these viruses may be particularly suitable for the formation of the protein coat in small, spherical, RNA-containing plant viruses.
