TURNIP YELLOW MOSAIC VIRUSTURNIP YELLOW MOSAIC VIRUS
Structural highlights
FunctionCAPSD_TYMV Self-assembles to form a T=3 icosahedral capsid composed of 180 copies of the capsid protein. The capsid encapsulates the single-stranded RNA genome (PubMed:15321716, PubMed:8784351). A pentameric unit may be lost during decapsidation (PubMed:15321716, PubMed:8784351).[1] [2] Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe structure of turnip yellow mosaic virus (TYMV) has been solved to 3.2 A resolution and an R-value of 18.7%. The structure is consistent with models based on low resolution X-ray and electron microscopy studies, with pentameric and hexameric protein aggregates protruding from the surface and forming deep valleys at the quasi three-fold axes. The N-terminal 26 residues of the A-subunit are disordered, while those of the B- and C-subunits are seen to interact around the interior of the quasi six-fold cluster where they form an annulus. The three histidine residues of each protein subunit are located in the interior and accessible for interaction with the RNA genome. The appearance of the interior surface of the virus capsid, along with buried surface area calculations, suggest that a pentameric unit is lost during decapsidation.
