Large ribosomal subunit protein uL16 (rplP) is a 141-residue protein from Deinococcus radiodurans (strain ATCC 13939 / DSM 20539 / JCM 16871 / CCUG 27074 / LMG 4051 / NBRC 15346 / NCIMB 9279 / VKM B-1422 / R1). This is its AlphaFold structure prediction, created 1 Aug 2025. UniProt accession: Q9RXJ5.

The mean pLDDT of this model is 95.3 (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 | 93% |
| 70 to 90 | Confident: backbone generally right | 7% |
| 50 to 70 | Low: treat with caution | 0% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Binds the 5S and 23S rRNAs and is also seen to make contacts with the A and P site tRNAs. Interacts with A site tRNA mimics, and is probably one of the key factors, along with a helix of the 23S rRNA, in positioning tRNA stems in the peptidyl-transferase center
Part of the 50S ribosomal subunit. Contacts the CTC protein (RL25)
