[[http://www.uniprot.org/uniprot/RS15_ECO57 RS15_ECO57]] 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 (By similarity). Forms an intersubunit bridge (bridge B4) with the 23S rRNA of the 50S subunit in the ribosome (By similarity). [[http://www.uniprot.org/uniprot/D7X302_ECOLX D7X302_ECOLX]] Involved in the binding of tRNA to the ribosomes.[HAMAP-Rule:MF_00508] [[http://www.uniprot.org/uniprot/A0A376HTV6_ECOLX A0A376HTV6_ECOLX]] 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/A0A0G3QJD8_9GAMM A0A0G3QJD8_9GAMM]] 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/L3PZ69_ECOLX L3PZ69_ECOLX]] 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/A0A090BZT4_ECOLX A0A090BZT4_ECOLX]] 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/D8A1L7_ECOMS D8A1L7_ECOMS]] 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/D7ZI16_ECOLX D7ZI16_ECOLX]] 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/T6N332_ECOLX T6N332_ECOLX]] Binds directly to 16S ribosomal RNA.[HAMAP-Rule:MF_00500] [[http://www.uniprot.org/uniprot/A0A074QGH8_ECOLX A0A074QGH8_ECOLX]] Binds together with S18 to 16S ribosomal RNA.[HAMAP-Rule:MF_00360][SAAS:SAAS00348112] [[http://www.uniprot.org/uniprot/F4SQ43_ECOLX F4SQ43_ECOLX]] Protein S19 forms a complex with S13 that binds strongly to the 16S ribosomal RNA.[HAMAP-Rule:MF_00531] [[http://www.uniprot.org/uniprot/V6FZ95_ECOLX V6FZ95_ECOLX]] 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]
