UniProt functional annotation for B5R541 | ||
|
|
|
|
|
|
||
| UniProt code: B5R541. |
|
||
| Organism: | |
Salmonella enteritidis PT4 (strain P125109). |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Salmonella. |
|
||
|
||
| Function: | |
Has low D-gluconate dehydratase activity (in vitro), suggesting that it has no significant role in D-gluconate degradation in vivo. Has no detectable activity with a panel of 70 other acid sugars (in vitro). {ECO:0000269|PubMed:24697546}. |
|
||
| Catalytic activity: | |
Reaction=D-gluconate = 2-dehydro-3-deoxy-D-gluconate + H2O; Xref=Rhea:RHEA:21612, ChEBI:CHEBI:15377, ChEBI:CHEBI:18391, ChEBI:CHEBI:57990; EC=4.2.1.39; Evidence={ECO:0000269|PubMed:24697546}; |
| Cofactor: | |
