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 | 90% |
| 70 to 90 | Confident: backbone generally right | 4% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 6% |
What pLDDT means and how to read it
Substrate recognition and binding subunit of the essential mitochondrial processing protease (MPP), which cleaves the mitochondrial sequence off newly imported precursors proteins
Heterodimer of MAS2 (alpha) and MAS1 (beta) subunits, forming the mitochondrial processing protease (MPP) in which MAS2 is involved in substrate recognition and binding and MAS1 is the catalytic subunit
Mitochondrion matrix
