The mean pLDDT of this model is 96.3 (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 | 98% |
| 70 to 90 | Confident: backbone generally right | 2% |
| 50 to 70 | Low: treat with caution | 0% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
With S4 and S5 plays an important role in translational accuracy
Part of the 30S ribosomal subunit (PubMed:10094780, PubMed:12093756, PubMed:12244297, PubMed:12379845, PubMed:12809609, PubMed:16272117, PubMed:27906160, PubMed:27906161, PubMed:27934701, PubMed:320034, PubMed:7556101). Contacts proteins S8 and S17. Interacts with ArfA (PubMed:27906160, PubMed:27906161). May interact with IF1 in the 30S initiation complex (By similarity)
