The mean pLDDT of this model is 92.3 (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 | 88% |
| 70 to 90 | Confident: backbone generally right | 10% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 1% |
What pLDDT means and how to read it
Component of the small ribosomal subunit (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). Required for pre-rRNA processing and maturation of 40S ribosomal subunits (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). During the assembly of the SSU processome in the nucleolus, many ribosome biogenesis factors, an…
