CC   -!- FUNCTION: Major role in the synthesis of nucleoside triphosphates other
CC       than ATP. The ATP gamma phosphate is transferred to the NDP beta
CC       phosphate via a ping-pong mechanism, using a phosphorylated active-site
CC       intermediate.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 2'-deoxyribonucleoside 5'-diphosphate + ATP = a 2'-
CC         deoxyribonucleoside 5'-triphosphate + ADP; Xref=Rhea:RHEA:44640,

CC         triphosphate + ADP; Xref=Rhea:RHEA:18113, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:57930, ChEBI:CHEBI:61557, ChEBI:CHEBI:456216; EC=2.7.4.6;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC   -!- SUBUNIT: Homohexamer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the NDK family. {ECO:0000305}.
