The mean pLDDT of this model is 79.9 (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 | 52% |
| 70 to 90 | Confident: backbone generally right | 23% |
| 50 to 70 | Low: treat with caution | 9% |
| Below 50 | Very low: often disordered regions | 16% |
What pLDDT means and how to read it
Non-catalytic subunit of the structure-specific, heterodimeric DNA endonuclease MUS81-EME2 which is involved in the maintenance of genome stability. In the complex, EME2 is required for DNA cleavage, participating in DNA recognition and bending (PubMed:17289582, PubMed:24371268, PubMed:24813886, PubMed:35290797). MUS81-EME2 cleaves 3'-flaps and nicked Holliday junctions, and exhibit limited endonuclease activity with 5' flaps and nicked double-stranded DNAs (PubMed:24371268). MUS81-EME2 which is active during the replication of DNA is more specifically involved in replication fork processing (PubMed:17289582, PubMed:24813886). Replication forks frequently encounter obstacles to their…
