The mean pLDDT of this model is 96.4 (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 | 98% |
| 70 to 90 | Confident: backbone generally right | 2% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Binds directly to 23S ribosomal RNA and is located at the A site of the peptidyltransferase center. It contacts the A and P site tRNAs (PubMed:8524654). One of the last ribosomal proteins to be assembled in the 50S subunit (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). It has an essential role in subunit assembly (PubMed:3298242)
Part of the 50S ribosomal subunit (PubMed:10094780, PubMed:12809609, PubMed:16272117, PubMed:24844575, PubMed:25310980, PubMed:27906160, PubMed:27906161, PubMed:27934701, PubMed:786730, PubMed:33639093, PubMed:38842932). Cross-links to the A and P site tRNAs (PubMed:8524654). Interacts with assembly factor DarP(YjgA) (PubMed:38842932)
