Protein: Small ribosomal subunit protein uS7 (30S ribosomal protein S7) (P02359)
Organism: Escherichia coli (strain K12)
Function: One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the head domain of the 30S subunit. Is located at the subunit interface close to the decoding center, where it has been shown to contact mRNA. Has been shown to contact tRNA in both the P and E sites; it probably blocks exit of the E site tRNA.
