Model confidence (pLDDT)

The mean pLDDT of this model is 92.6 (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	14%
50 to 70	Low: treat with caution	1%
Below 50	Very low: often disordered regions	0%

What pLDDT means and how to read it

Function

Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) which catalyzes electron transfer from NADH through the respiratory chain, using ubiquinone as an electron acceptor. Essential for the catalytic activity and assembly of complex I

Subunit structure

Core subunit of respiratory chain NADH dehydrogenase (Complex I) which is composed of 45 different subunits

Subcellular location

Mitochondrion inner membrane
