Protein

30S ribosomal protein S8

Gene

rpsH

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.By similarity
Protein S8 is a translational repressor protein, it controls the translation of the spc operon by binding to its mRNA.1 Publication
