Model confidence (pLDDT)

The mean pLDDT of this model is 93.7 (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	89%
70 to 90	Confident: backbone generally right	7%
50 to 70	Low: treat with caution	3%
Below 50	Very low: often disordered regions	1%

What pLDDT means and how to read it

Function

With S4 and S5 plays an important role in translational accuracy

Subunit structure

Part of the 30S ribosomal subunit (PubMed:11007480, PubMed:11014182, PubMed:11014183, PubMed:11163189, PubMed:11228145, PubMed:11283358, PubMed:11296217, PubMed:11340196, PubMed:11511350, PubMed:11866529, PubMed:25775268, PubMed:26792896). Contacts proteins S8 and S17 (PubMed:11866529). Interacts with IF1 in the 30S initiation complex (PubMed:11228145)
