The mean pLDDT of this model is 66.1 (low 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 | 2% |
| 70 to 90 | Confident: backbone generally right | 56% |
| 50 to 70 | Low: treat with caution | 17% |
| Below 50 | Very low: often disordered regions | 25% |
What pLDDT means and how to read it
Interacts with the internal control region (ICR) of approximately 50 bases within the 5S RNA genes, is required for correct transcription of these genes by RNA polymerase III. Also binds the transcribed 5S RNA's
