Function

[A0A063X754_BACIU] Binds to 23S rRNA. Forms part of two intersubunit bridges in the 70S ribosome.[HAMAP-Rule:MF_01367][RuleBase:RU003950] [A0A063XIS2_BACIU] This protein binds to 23S rRNA in the presence of protein L20.[HAMAP-Rule:MF_01363][RuleBase:RU000562][SAAS:SAAS00352917] [A0A063X745_BACIU] One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.[HAMAP-Rule:MF_01325][RuleBase:RU003906] [A0A063XCP1_BACIU] Binds to the 23S rRNA.[HAMAP-Rule:MF_01341][SAAS:SAAS00124822] [A0A063XHU6_BACIU] This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.[HAMAP-Rule:MF_00402][RuleBase:RU000559] [A0A063XCB6_BACIU] One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome.[HAMAP-Rule:MF_01320] [F5HRT3_BACIU] The globular domain of the protein is located near the polypeptide exit tunnel on the outside of the subunit, while an extended beta-hairpin is found that lines the wall of the exit tunnel in the center of the 70S ribosome.[HAMAP-Rule:MF_01331] This protein binds specifically to 23S rRNA; its binding is stimulated by other ribosomal proteins, e.g., L4, L17, and L20. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome.[HAMAP-Rule:MF_01331][RuleBase:RU004008] [F5HRS7_BACIU] One of the proteins that surrounds the polypeptide exit tunnel on the outside of the subunit.[HAMAP-Rule:MF_01326] One of two assembly initiator proteins, it binds directly to the 5'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.[HAMAP-Rule:MF_01326] [A0A063X8U6_BACIU] Forms part of the polypeptide exit tunnel.[HAMAP-Rule:MF_01328] One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome.[HAMAP-Rule:MF_01328] [A0A063XFC1_BACIU] Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit.[HAMAP-Rule:MF_00382][RuleBase:RU000560] [A0A063XB36_BACIU] One of the early assembly proteins it binds 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome. Forms the main docking site for trigger factor binding to the ribosome.[HAMAP-Rule:MF_01369] [A0A063XCH0_BACIU] This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.[HAMAP-Rule:MF_01366][RuleBase:RU003878][SAAS:SAAS00725369]
