| UniProt functional annotation for P42920 | |||
| UniProt code: P42920. |
| Organism: | Bacillus subtilis (strain 168). | |
| Taxonomy: | Bacteria; Firmicutes; Bacilli; Bacillales; Bacillaceae; Bacillus. | |
| Function: | 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 (By similarity). Strongly stimulates 23S rRNA precursor processing by mini-ribonuclease 3 (MrnC); 20-30% DMSO can replace L3, suggesting the protein may alter rRNA conformation. {ECO:0000255|HAMAP- Rule:MF_01325, ECO:0000269|PubMed:19154332}. | |
| Subunit: | Part of the 50S ribosomal subunit (PubMed:30126986). Forms a cluster with proteins L14 and L19 (By similarity). Interacts with RNA helicase CshA (PubMed:23175651). {ECO:0000255|HAMAP-Rule:MF_01325, ECO:0000269|PubMed:23175651, ECO:0000269|PubMed:30126986}. | |
| Similarity: | Belongs to the universal ribosomal protein uL3 family. {ECO:0000255|HAMAP-Rule:MF_01325}. | |
