The mean pLDDT of this model is 91.1 (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 | 74% |
| 70 to 90 | Confident: backbone generally right | 22% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Constitutes, with BamD, the core component of the assembly machinery
Part of the Bam complex, which is composed of the outer membrane protein BamA, and four lipoproteins BamB, BamC, BamD and BamE

UniProt lists no experimental PDB structure for this protein, so the AlphaFold prediction is the main 3D model available.
MolViewer loads the AlphaFold model straight from AlphaFold DB into your browser. Show it as a cartoon, color by pLDDT, measure distances and angles, and load a PDB structure next to it to compare.
