The mean pLDDT of this model is 91.6 (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 | 82% |
| 70 to 90 | Confident: backbone generally right | 9% |
| 50 to 70 | Low: treat with caution | 4% |
| Below 50 | Very low: often disordered regions | 5% |
What pLDDT means and how to read it
This protein is a negative regulator for the gene expression of the lactose/galactose metabolic genes. It binds to GAL4 and so blocks transcriptional activation by it, in the absence of an inducing sugar
