The mean pLDDT of this model is 89.7 (confident 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 | 84% |
| 70 to 90 | Confident: backbone generally right | 8% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 7% |
What pLDDT means and how to read it
Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation
Part of the 30S ribosomal subunit. Forms a tight complex with proteins S10 and S14
UniProt lists no experimental PDB structure for this protein, so the AlphaFold prediction is the main 3D model available.
MolViewer loads the AlphaFold model straight from AlphaFold DB into your browser. Show it as a cartoon, color by pLDDT, measure distances and angles, and load a PDB structure next to it to compare.
