The mean pLDDT of this model is 93.3 (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 | 88% |
| 70 to 90 | Confident: backbone generally right | 10% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain (PubMed:25759169). F-type ATP synthases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk (PubMed:27791192). During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation (By similarity). Subunits alpha/ATP1 and beta/ATP2 form the…
F-type ATP synthases have 2 components, the catalytic core F(1) and the membrane-embedded component F(0), linked together by a central stalk and a peripheral stalk (PubMed:27791192). The central stalk, also called rotor shaft, is often seen as part of F(1) (PubMed:27791192). The peripheral stalk is seen as part of F(0). F(0) contains the membrane channel next to the rotor (PubMed:27791192).…
