Model confidence (pLDDT)

The mean pLDDT of this model is 89.1 (confident 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	67%
70 to 90	Confident: backbone generally right	26%
50 to 70	Low: treat with caution	5%
Below 50	Very low: often disordered regions	2%

What pLDDT means and how to read it

Function

DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates
