The mean pLDDT of this model is 85.6 (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 | 18% |
| 70 to 90 | Confident: backbone generally right | 80% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 1% |
What pLDDT means and how to read it
Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors. Required to recruit RqcH, which is part of the ribosome quality control system (RQC), to stalled 50S ribosomal subunits (PubMed:34255840)
Part of the ribosomal stalk of the 50S ribosomal subunit. Interacts with L10 and the large rRNA to form the base of the stalk. L10 forms an elongated spine to which 2 L12 dimers bind in a sequential fashion forming a pentameric L10(L12)2(L12)2 complex. In stalled/isolated 50S subunits interacts with RqcH (PubMed:33259811, PubMed:33259810, PubMed:34255840)
