RL (er) Plant Gene Register PGR97-010(1997).
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 ChEBI:CHEBI:30616, ChEBI:CHEBI:61560, ChEBI:CHEBI:73316,
CC ChEBI:CHEBI:456216; EC=2.7.4.6;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ribonucleoside 5'-diphosphate + ATP = a ribonucleoside 5'-
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 -!- SIMILARITY: Belongs to the NDK family. {ECO:0000305}.
