The mean pLDDT of this model is 94.3 (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 | 90% |
| 70 to 90 | Confident: backbone generally right | 4% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 1% |
What pLDDT means and how to read it
Located on the outer edge of the platform on the body of the 30S subunit
Part of the 30S ribosomal subunit. Forms a tight heterodimer with protein bS18. May make transient contacts with protein uL2 of the 50S subunit during translation
