UniProt functional annotation for P31473 | ||
|
|
|
|
|
|
||
| UniProt code: P31473. |
|
||
| Organism: | |
Escherichia coli (strain K12). |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia. |
|
||
|
||
| Function: | |
Functions as an ATPase. May play a role in metal insertion (metal-chelatase) or as a chaperone. |
|
||
| Activity regulation: | |
The complex formed with CadA represents a possible means of regulating RavA activity in response to acid stress conditions. This interaction results in an increase in RavA ATPase activity. |
| Biophysicochemical properties: | |
Kinetic parameters: KM=790 uM for ATP (at pH 7.5); Note=RavA also has GTPase activity.; pH dependence: Optimum pH is 7.5.; |
| Subunit: | |
Hexameric oligomer. Interactions of five RavA oligomers with two CadA decamers. Possible formation of a ternary complex RavA-ViaA- CadA. {ECO:0000269|PubMed:16301313}. |
| Subcellular location: | |
Cytoplasm. |
| Induction: | |
Expression is sigma S-dependent. |
| Similarity: | |
Belongs to the RavA family. {ECO:0000305}. |
