UniProt functional annotation for P0A7M9 | ||
|
|
|
|
|
|
||
| UniProt code: P0A7M9. |
|
||
| Organism: | |
Escherichia coli (strain K12). |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia. |
|
||
|
||
| Function: | |
Binds the 23S rRNA. {ECO:0000250}. |
|
||
| Cofactor: | |
Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000269|PubMed:22196016}; Note=Binds 1 zinc ion per subunit. Only 1 ligand appears to be Cys, the other are thought to be His and either backbone amides or solvent (PubMed:22196016). {ECO:0000269|PubMed:22196016}; |
| Subunit: | |
Part of the 50S ribosomal subunit. {ECO:0000269|PubMed:10094780, ECO:0000269|PubMed:16272117, ECO:0000269|PubMed:27906160, ECO:0000269|PubMed:27906161, ECO:0000269|PubMed:27934701, ECO:0000269|PubMed:339950}. |
| Ptm: | |
Proteolytically cleaved by protease VII to yield a peptide lacking residues 63-70. It is not clear if this is due to protein degradation or is a bona fide processing event in the strain used in PubMed:339950 and PubMed:10556732. In strains B, D10, MRE-600 and Q13 the only protein seen in PubMed:10556732 was full-length; the last 7 amino acids were sequenced only for strain MRE-600. {ECO:0000269|PubMed:10556732, ECO:0000269|PubMed:339950}. |
| Mass spectrometry: | |
Mass=7871.0; Method=MALDI; Evidence={ECO:0000269|PubMed:10094780}; |
| Similarity: | |
Belongs to the bacterial ribosomal protein bL31 family. Type A subfamily. {ECO:0000305}. |
