Model confidence (pLDDT)

The mean pLDDT of this model is 94.4 (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	94%
70 to 90	Confident: backbone generally right	5%
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

One of the primary rRNA binding proteins, it binds directly to 16S rRNA central domain where it helps coordinate assembly of the platform of the 30S subunit

Subunit structure

Part of the 30S ribosomal subunit (PubMed:10094780, PubMed:12244297, PubMed:12809609, PubMed:16272117, PubMed:27906160, PubMed:27906161, PubMed:27934701, PubMed:28077875, PubMed:365698). Contacts proteins S5 and S12 (By similarity)
