The mean pLDDT of this model is 66.1 (low 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 | 0% |
| 70 to 90 | Confident: backbone generally right | 47% |
| 50 to 70 | Low: treat with caution | 33% |
| Below 50 | Very low: often disordered regions | 20% |
What pLDDT means and how to read it
Subunit of the protein translocation channel SecYEG
Component of the Sec protein translocase complex. Heterotrimer consisting of SecY, SecE and SecG subunits. The heterotrimers can form oligomers, although 1 heterotrimer is thought to be able to translocate proteins. Interacts with SecDF, and other proteins may be involved. The channel interacts with SecA via subunit SecY
