The mean pLDDT of this model is 90.4 (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 | 71% |
| 70 to 90 | Confident: backbone generally right | 23% |
| 50 to 70 | Low: treat with caution | 6% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Binds together with bS18 to 16S ribosomal RNA
Part of the 30S ribosomal subunit (PubMed:10094780, PubMed:12244297, PubMed:12809609, PubMed:16272117, PubMed:27906160, PubMed:27906161, PubMed:27934701, PubMed:28077875, PubMed:328274). Interacts weakly with uL2 in one of the 3.5 A resolved structures (PubMed:16272117)
