The mean pLDDT of this model is 98.1 (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 | 100% |
| 70 to 90 | Confident: backbone generally right | 1% |
| 50 to 70 | Low: treat with caution | 0% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Removes ADP-ribose from aspartate and glutamate residues in proteins bearing a single ADP-ribose moiety (PubMed:23474712, PubMed:23474714). Inactive towards proteins bearing poly-ADP-ribose (PubMed:23474712, PubMed:23474714). Catalyzes removal of a phosphate group from ADP-ribose 1''-phosphate (Appr1p), but with low efficiency (PubMed:15902274)
