Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rickettsiales › Rickettsiaceae › Rickettsieae › Rickettsia › typhus group

Protein attributes

Sequence length	140 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

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. HAMAP MF_00451
Catalytic activity	ATP + nucleoside diphosphate = ADP + nucleoside triphosphate. HAMAP MF_00451
Cofactor	Magnesium By similarity. HAMAP MF_00451
Subunit structure	Homotetramer By similarity. HAMAP MF_00451
Subcellular location	Cytoplasm By similarity HAMAP MF_00451.
Sequence similarities	Belongs to the NDK family.
