The mean pLDDT of this model is 92.5 (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 | 85% |
| 70 to 90 | Confident: backbone generally right | 11% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate
Monomer (By similarity). Found in a complex with LTF, CLU, EPPIN and SEMG1 (By similarity). Interacts with E.coli outer membrane protein C (OmpC) (PubMed:11473113). Found in a complex with MPO and LTF; interacts directly with CP, allows Fe(3+) incorporation into LTF and activation of CP ferroxidase activity (By similarity)
