    Functioni

    Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP. It can use ATP and other nucleoside triphosphates (GTP,UTP) as well as inorganic polyphosphate (poly(P)) as a source of phosphorus. NAD is the preferred substrate for the kinase, but NADH can also be used as phosphoryl acceptor.1 PublicationUniRule annotation

    Kineticsi

    1. KM=0.29 mM for ATP (at pH 6 and 70 degrees Celsius)1 Publication
    2. KM=0.3 mM for NAD (with poly(P) as phosphoryl donor at pH 6.8 and 70 degrees Celsius)1 Publication
    3. KM=0.4 mM for NAD (with ATP as phosphoryl donor at pH 6.8 and 70 degrees Celsius)1 Publication

    pH dependencei

    Optimum pH is 6.8. At 70 degrees Celsius for 60 minutes, the enzyme does not lose activity in a pH range of 4.0 to 10.5.1 Publication

    Temperature dependencei

    Extremely high thermostability. Upon heating at 95 degrees Celsius for 10 minutes the kinase activity is not lost, but about 80% of the activity is lost upon incubation at 100 degrees Celsius for 10 minutes.1 Publication
