The mean pLDDT of this model is 85.8 (confident overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.
| pLDDT band | Meaning | Share of residues |
|---|---|---|
| Above 90 | Very high: backbone and side chains are usually accurate | 62% |
| 70 to 90 | Confident: backbone generally right | 23% |
| 50 to 70 | Low: treat with caution | 8% |
| Below 50 | Very low: often disordered regions | 7% |
What pLDDT means and how to read it
Capsid protein that self-assembles to form the pseudo-hexameric capsomers of the icosahedral capsid (PubMed:31624094). The capsid is constructed of 2760 pseudo-hexameric capsomers and 12 pentameric capsomers, with a T=277 symmetry, about 200 nm in diameter (PubMed:31624094). The capsid encapsulates the DNA-containing nucleoid, the core shell and the inner membrane (PubMed:9580160). Plays an essential role in virion assembly (PubMed:9580160). Involved in virus attachment to the host cell (PubMed:8764090)
Homotrimer (PubMed:31624094). The membrane-bound form, but not the cytosolic one, assembles into large complexes (PubMed:9573294). Interacts with the minor capsid proteins M1249L and p17; these interactions form a rigid zipper structure that stabilizes the capsomers (PubMed:31624094)
