The mean pLDDT of this model is 68.8 (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 | 30% |
| 70 to 90 | Confident: backbone generally right | 28% |
| 50 to 70 | Low: treat with caution | 11% |
| Below 50 | Very low: often disordered regions | 31% |
What pLDDT means and how to read it
Required for the insertion of some light harvesting chlorophyll-binding proteins (LHCP) into the chloroplast thylakoid membrane. Required for the insertion of LHCB1, LHCB4.1 and LHCB5 proteins into thylakoid membrane, while it is not required for insertion of proteins PsbX, PsbW and PsbY
Homodimer. Forms a complex with CPFTSY and the signal recognition particle (cpSRP). Interacts (via C-terminus) with CAO/cpSRP43 (via chromodomains 2 and 3) and with LHCP. Interacts with PAM68, SECE1 and SCY1 (PubMed:12217076, PubMed:14517205, PubMed:15988575, PubMed:17513500, PubMed:20018841, PubMed:20828566, PubMed:20923938, PubMed:21832051).
