[[http://www.uniprot.org/uniprot/E2RXU4_PSEAI E2RXU4_PSEAI]] Located on the platform of the 30S subunit, it bridges several disparate RNA helices of the 16S rRNA. Forms part of the Shine-Dalgarno cleft in the 70S ribosome.[HAMAP-Rule:MF_01310] [[http://www.uniprot.org/uniprot/A0A2V3F2U6_PSEAI A0A2V3F2U6_PSEAI]] 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, probably blocks exit of the E-site tRNA.[HAMAP-Rule:MF_00480] [[http://www.uniprot.org/uniprot/E2RXT5_PSEAI E2RXT5_PSEAI]] One of the primary rRNA binding proteins, it binds specifically to the 5'-end of 16S ribosomal RNA.[HAMAP-Rule:MF_01345] [[http://www.uniprot.org/uniprot/A0A2V3DLV3_PSEAI A0A2V3DLV3_PSEAI]] Binds as a heterodimer with protein S6 to the central domain of the 16S rRNA, where it helps stabilize the platform of the 30S subunit.[HAMAP-Rule:MF_00270] [[http://www.uniprot.org/uniprot/E2RXU3_PSEAI E2RXU3_PSEAI]] Located at the top of the head of the 30S subunit, it contacts several helices of the 16S rRNA. In the 70S ribosome it contacts the 23S rRNA (bridge B1a) and protein L5 of the 50S subunit (bridge B1b), connecting the 2 subunits; these bridges are implicated in subunit movement. Contacts the tRNAs in the A and P-sites.[HAMAP-Rule:MF_01315] [[http://www.uniprot.org/uniprot/A0A069Q263_PSEAI A0A069Q263_PSEAI]] Binds together with S18 to 16S ribosomal RNA.[HAMAP-Rule:MF_00360][SAAS:SAAS00348112] [[http://www.uniprot.org/uniprot/A0A140S919_PSEAI A0A140S919_PSEAI]] Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation.[HAMAP-Rule:MF_01309] [[http://www.uniprot.org/uniprot/A0A071L394_PSEAI A0A071L394_PSEAI]] 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.[HAMAP-Rule:MF_00403][RuleBase:RU003623] With S4 and S5 plays an important role in translational accuracy.[HAMAP-Rule:MF_00403][RuleBase:RU003623] [[http://www.uniprot.org/uniprot/E2RXT8_PSEAI E2RXT8_PSEAI]] 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.[HAMAP-Rule:MF_00537] [[http://www.uniprot.org/uniprot/A0A071L3R7_PSEAI A0A071L3R7_PSEAI]] Forms an intersubunit bridge (bridge B4) with the 23S rRNA of the 50S subunit in the ribosome.[HAMAP-Rule:MF_01343] 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.[HAMAP-Rule:MF_01343][RuleBase:RU004524] [[http://www.uniprot.org/uniprot/A0A072ZDZ9_PSEAI A0A072ZDZ9_PSEAI]] Binds directly to 16S ribosomal RNA.[HAMAP-Rule:MF_00500] [[http://www.uniprot.org/uniprot/E2RXT9_PSEAI E2RXT9_PSEAI]] 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.[HAMAP-Rule:MF_01302] [[http://www.uniprot.org/uniprot/A0A072ZDF7_PSEAI A0A072ZDF7_PSEAI]] One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.[HAMAP-Rule:MF_01306] With S5 and S12 plays an important role in translational accuracy.[HAMAP-Rule:MF_01306] [[http://www.uniprot.org/uniprot/E2RXT0_PSEAI E2RXT0_PSEAI]] Involved in the binding of tRNA to the ribosomes.[HAMAP-Rule:MF_00508] [[http://www.uniprot.org/uniprot/E2RXT2_PSEAI E2RXT2_PSEAI]] Protein S19 forms a complex with S13 that binds strongly to the 16S ribosomal RNA.[HAMAP-Rule:MF_00531] [[http://www.uniprot.org/uniprot/A0A241XG65_PSEAI A0A241XG65_PSEAI]] Located at the back of the 30S subunit body where it stabilizes the conformation of the head with respect to the body.[HAMAP-Rule:MF_01307][SAAS:SAAS00085417] With S4 and S12 plays an important role in translational accuracy.[HAMAP-Rule:MF_01307][SAAS:SAAS00085429]
