Protein attributes

Sequence length	137 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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.
Subunit structure	Homotetramer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the NDK family.
