UniProt functional annotation for P17291

UniProt codes: P17291, Q5SHN4.

Organism: Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579).
Taxonomy: Bacteria; Deinococcus-Thermus; Deinococci; Thermales; Thermaceae; Thermus.
Function: One of the primary rRNA binding proteins, it binds directly to 3'-end of the 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. Binds mRNA and the E site tRNA blocking its exit path in the ribosome. This blockage implies that this section of the ribosome must be able to move to release the deacetylated tRNA.
Subunit: Part of the 30S ribosomal subunit. Contacts proteins S9 and S11. Binds to the C-terminus of IF3 and to the C-terminus of Era.
Mass spectrometry: Mass=17886; Method=MALDI; Range=2-156; Evidence={ECO:0000269|PubMed:16287167};
Similarity: Belongs to the ribosomal protein S7P family. {ECO:0000305}.
