UniProt functional annotation for Q83WH5 | ||
|
|
|
|
|
|
||
| UniProt code: Q83WH5. |
|
||
| Organism: | |
Halomonas sp. #593. |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Oceanospirillales; Halomonadaceae; Halomonas. |
|
||
|
||
| Function: | |
Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate. {ECO:0000256|HAMAP-Rule:MF_00451}. |
|
||
| Catalytic activity: | |
Reaction=a 2'-deoxyribonucleoside 5'-diphosphate + ATP = a 2'- deoxyribonucleoside 5'-triphosphate + ADP; Xref=Rhea:RHEA:44640, ChEBI:CHEBI:30616, ChEBI:CHEBI:61560, ChEBI:CHEBI:73316, ChEBI:CHEBI:456216; EC=2.7.4.6; Evidence={ECO:0000256|HAMAP- Rule:MF_00451, ECO:0000256|RuleBase:RU004013}; |
