The mean pLDDT of this model is 94.5 (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 | 91% |
| 70 to 90 | Confident: backbone generally right | 7% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 1% |
What pLDDT means and how to read it
Component of the ribosome, a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell. The small ribosomal subunit (SSU) binds messenger RNAs (mRNAs) and translates the encoded message by selecting cognate aminoacyl-transfer RNA (tRNA) molecules. The large subunit (LSU) contains the ribosomal catalytic site termed the peptidyl transferase center (PTC), which catalyzes the formation of peptide bonds, thereby polymerizing the amino acids delivered by tRNAs into a polypeptide chain. The nascent polypeptides leave the ribosome through a tunnel in the LSU and interact with protein factors that function in enzymatic processing, targeting, and the membrane insertion…
Component of the large ribosomal subunit (LSU). Part of the 5S RNP complex, which is a LSU subcomplex composed of the 5S RNA, RPL5 and RPL11 (PubMed:24120868, PubMed:37291423). Component of a hexameric 5S RNP precursor complex, composed of 5S RNA, RRS1, RPF2/BXDC1, RPL5, RPL11 and HEATR3; this complex acts as a precursor for ribosome assembly (PubMed:37291423). Interacts with isoform 1 of NVL in…
