The mean pLDDT of this model is 95.3 (very high 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 | 95% |
| 70 to 90 | Confident: backbone generally right | 5% |
| 50 to 70 | Low: treat with caution | 0% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Component of the large ribosomal subunit. The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell
Part of the 50S ribosomal subunit (PubMed:11677599, PubMed:11733066, PubMed:12535524, PubMed:12623020, PubMed:12665853, PubMed:15059283, PubMed:15554968). Forms a bridge to the 30S subunit in the 70S ribosome (By similarity)
