| [[http://www.uniprot.org/uniprot/RSHX_THETH RSHX_THETH]] Binds at the top of the head of the 30S subunit. It stabilizes a number of different RNA elements and thus is important for subunit structure (By similarity). [[http://www.uniprot.org/uniprot/RS7_THET8 RS7_THET8]] 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.[HAMAP-Rule:MF_00480_B] [[http://www.uniprot.org/uniprot/RS17_THETH RS17_THETH]] One of the primary rRNA binding proteins, it binds specifically to the 5'-end of 16S ribosomal RNA (By similarity). [[http://www.uniprot.org/uniprot/RS16_THETH RS16_THETH]] Binds to the lower part of the body of the 30S subunit, where it stabilizes two of its domains. [[http://www.uniprot.org/uniprot/RS6_THETH RS6_THETH]] Located on the outer edge of the platform on the body of the 30S subunit (By similarity). [[http://www.uniprot.org/uniprot/RS12_THETH RS12_THETH]] With S4 and S5 plays an important role in translational accuracy (By similarity).[HAMAP-Rule:MF_00403_B] Interacts with and stabilizes bases of the 16S rRNA that are involved in tRNA selection in the A site and with the mRNA backbone. Located at the interface of the 30S and 50S subunits, it traverses the body of the 30S subunit contacting proteins on the other side and probably holding the rRNA structure together. The combined cluster of proteins S8, S12 and S17 appears to hold together the shoulder and platform of the 30S subunit (By similarity).[HAMAP-Rule:MF_00403_B] [[http://www.uniprot.org/uniprot/RS14Z_THETH RS14Z_THETH]] Binds 16S rRNA, required for the assembly of 30S particles and may also be responsible for determining the conformation of the 16S rRNA at the A site (By similarity). [[http://www.uniprot.org/uniprot/RS15_THETH RS15_THETH]] One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the platform of the 30S subunit by binding and bridging several RNA helices of the 16S rRNA. Forms an intersubunit bridge (bridge B4) with the 23S rRNA of the 50S subunit in the ribosome (By similarity). [[http://www.uniprot.org/uniprot/RS8_THETH RS8_THETH]] 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). [[http://www.uniprot.org/uniprot/RS4_THET8 RS4_THET8]] One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the body and platform of the 30S subunit. Binds mRNA in the 70S ribosome, positioning it for translation.[HAMAP-Rule:MF_01306_B] [[http://www.uniprot.org/uniprot/RS19_THETH RS19_THETH]] Protein S19 forms a complex with S13 that binds strongly to the 16S ribosomal RNA (By similarity). [[http://www.uniprot.org/uniprot/RS10_THETH RS10_THETH]] Involved in the binding of tRNA to the ribosomes (By similarity). [[http://www.uniprot.org/uniprot/RS5_THETH RS5_THETH]] With S4 and S12 plays an important role in translational accuracy (By similarity).[HAMAP-Rule:MF_01307_B] Located at the back of the 30S subunit body where it stabilizes the conformation of the head with respect to the body (By similarity).[HAMAP-Rule:MF_01307_B] | | [https://www.uniprot.org/uniprot/RS2_THET8 RS2_THET8] Spans the head-body hinge region of the 30S subunit. Is loosely associated with the 30S subunit.[HAMAP-Rule:MF_00291_B] |
