The mean pLDDT of this model is 61.1 (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 | 28% |
| 70 to 90 | Confident: backbone generally right | 19% |
| 50 to 70 | Low: treat with caution | 11% |
| Below 50 | Very low: often disordered regions | 43% |
What pLDDT means and how to read it
Protease that catalyzes two essential functions in the SUMO pathway: processing of full-length SMT3 to its mature form and deconjugation of SMT3 from targeted proteins. Has an essential role in the G2/M phase of the cell cycle
