The mean pLDDT of this model is 95.6 (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 | 97% |
| 70 to 90 | Confident: backbone generally right | 3% |
| 50 to 70 | Low: treat with caution | 0% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
One of the last ribosomal proteins to be assembled in the 50S subunit, it contacts a number of helices in the 23S rRNA, acting as molecular glue (PubMed:33639093). The simultaneous presence of uL16 and bL36 probably triggers ObgE's GTPase activity and eventual dissociation from the mature 50S ribosomal subunit (PubMed:33639093)
