UniProt functional annotation for P0A7X3 | ||
|
|
|
|
|
|
||
| UniProt codes: P0A7X3, P02363. |
|
||
| Organism: | |
Escherichia coli (strain K12). |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia. |
|
||
|
||
| Function: | |
The C-terminal tail plays a role in the affinity of the 30S P site for different tRNAs. Mutations that decrease this affinity are suppressed in the 70S ribosome. {ECO:0000269|PubMed:15308780}. |
|
||
| Subunit: | |
Part of the 30S ribosomal subunit (PubMed:1091515, PubMed:7556101, PubMed:10094780, PubMed:12809609, PubMed:16272117, PubMed:27934701, PubMed:12244297, PubMed:27906160, PubMed:27906161, PubMed:28077875). Contacts 16S rRNA (PubMed:7556101). Cross-links to the P site tRNA and weakly to the A site tRNA (PubMed:8524654, PubMed:15308780). {ECO:0000269|PubMed:10094780, ECO:0000269|PubMed:1091515, ECO:0000269|PubMed:12244297, ECO:0000269|PubMed:12809609, ECO:0000269|PubMed:15308780, ECO:0000269|PubMed:16272117, ECO:0000269|PubMed:27906160, ECO:0000269|PubMed:27906161, ECO:0000269|PubMed:27934701, ECO:0000269|PubMed:28077875, ECO:0000269|PubMed:7556101, ECO:0000269|PubMed:8524654}. |
| Mass spectrometry: | |
Mass=14723.3; Method=MALDI; Evidence={ECO:0000269|PubMed:10094780}; |
| Similarity: | |
Belongs to the universal ribosomal protein uS9 family. {ECO:0000305}. |
