The mean pLDDT of this model is 91.0 (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 | 73% |
| 70 to 90 | Confident: backbone generally right | 24% |
| 50 to 70 | Low: treat with caution | 3% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
GTP hydrolase that promotes the GTP-dependent binding of aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis
Monomer. Heterotetramer composed of two EF-Ts.EF-Tu dimer complexes (By similarity)
Cytoplasm, Cell inner membrane
