The mean pLDDT of this model is 88.0 (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 | 55% |
| 70 to 90 | Confident: backbone generally right | 42% |
| 50 to 70 | Low: treat with caution | 3% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) which catalyzes electron transfer from NADH through the respiratory chain, using ubiquinone as an electron acceptor (PubMed:29915388, PubMed:38575788). Part of the enzyme membrane arm which is embedded in the lipid bilayer and involved in proton translocation (PubMed:29915388)
Core subunit of respiratory chain NADH dehydrogenase (Complex I) which is composed of 45 different subunits
Mitochondrion inner membrane
