The mean pLDDT of this model is 91.9 (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 | 89% |
| 70 to 90 | Confident: backbone generally right | 5% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 4% |
What pLDDT means and how to read it
Component of the small ribosomal subunit. The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell
Part of the 30S ribosomal subunit (PubMed:10094780, PubMed:12244297, PubMed:12809609, PubMed:16272117, PubMed:27906160, PubMed:27906161, PubMed:27934701, PubMed:28077875, PubMed:363452, PubMed:4273819). Contacts proteins uS4 and uS8. With proteins uS3 and uS4 encircles the mRNA as it enters the ribosome, which may play a role in mRNA helicase processivity (PubMed:15652481). Can be cross-linked…
