The mean pLDDT of this model is 71.3 (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 | 10% |
| 70 to 90 | Confident: backbone generally right | 49% |
| 50 to 70 | Low: treat with caution | 27% |
| Below 50 | Very low: often disordered regions | 14% |
What pLDDT means and how to read it
Complement inhibitor (PubMed:27018802). Prevents complement-mediated C5 activation by binding to C5 (PubMed:27018802). Binds C5 at a different binding site than the other tick complement inhibitors OmCI and CirpT1, and the drug eculizumab (By similarity)
