The mean pLDDT of this model is 53.8 (low 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 | 0% |
| 70 to 90 | Confident: backbone generally right | 3% |
| 50 to 70 | Low: treat with caution | 63% |
| Below 50 | Very low: often disordered regions | 34% |
What pLDDT means and how to read it
Vasoconstrictor activity. These toxins cause cardiac arrest probably as a result of coronary vasospasm
