Protein

30S ribosomal protein S18

Gene

rpsR

Organism
Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Located on the back of the platform of the 30S subunit where it stabilizes the close packing of several RNA helices of the 16S rRNA. Forms part of the Shine-Dalgarno cleft in the 70S ribosome, where it probably interacts with the Shine-Dalgarno helix.
