The mean pLDDT of this model is 78.1 (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 | 62% |
| 70 to 90 | Confident: backbone generally right | 14% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 23% |
What pLDDT means and how to read it
Avirulence protein. Acts as a transcription factor in rice, inducing expression of a number of host genes including SWEET11 (Os8N3, XA13, AC Q6YZF3) in susceptible plants with the Xa13 allele. Plants with the xa13 allele, which has an altered promoter, are resistant to bacterial blight caused by this bacterial strain and do not induce SWEET11. The xa13 allele elicits an atypical hypersensitive response (HR). PthXo1 binds SWEET11 promoter DNA in a sequence-specific manner
