Probing binding requirements of NAD kinase with modified substrate (NAD) analogues

Bioorganic and Medicinal Chemistry Letters, 2007
Synthesis of novel NAD(+) analogues that cannot be phosphorylated by NAD kinase is reported. In these analogues the C2' hydroxyl group of the adenosine moiety was replaced by fluorine in the ribo or arabino configuration (1 and 2, respectively) or was inverted into arabino configuration to give compound 3.

NAD+ kinase—A review

International Journal of Biochemistry, 1985
NAD+ kinase catalyzes the only (known) biochemical reaction leading to the production of NADP+ from NAD+. Most evidence indicates it is found in the cytoplasm, but reports of its presence in (other) cell bodies can not be discounted. Viewed as a protein, our knowledge of NADK composition and architecture is rudimentary.

Activation of calmodulin-dependent NAD kinase by trypsin

BBA - Proteins and Proteomics, 1982
Sea urchin egg NAD+ kinase (ATP:NAD+ 2'-phosphotransferase, EC 2.7.1.23), a calmodulin-dependent enzyme, can be activated by a moderate treatment with trypsin in a similar fashion to calmodulin. Stimulation by trypsin is dependent on its concentration (half-maximal dose: 1.5 microgram/ml) but independent of the presence of calcium.

Diacylglyceride kinases, sphingosine kinases and NAD kinases: distant relatives of 6-phosphofructokinases

Trends in Biochemical Sciences, 2002
Diacylglyceride kinases, sphingosine kinases, NAD kinases and 6-phosphofructokinases are thought to be related despite large evolution of their sequences. Discovery of a common signature has led to the suggestion that they possess a similar phosphate-donor-binding site and a similar phosphorylation mechanism. The substrate- and allosteric-binding sites

THE INDUCTION OF NAD KINASE BY DDT IN TRIATOMA INFESTANS

Canadian Journal of Biochemistry, 1967
The NAD kinase (EC 2.7.1.23) from Triatoma infestans has been purified and a specific antiserum against it prepared. Immunochemical techniques have shown that the increase in the levels of NAD kinase in nymphs of T. infestans is accompanied by an increase in the amount of enzyme protein.

PROPERTIES OF RAT BRAIN NAD‐KINASE

Journal of Neurochemistry, 1970
Abstract— NAD‐kinase was purified from rat brain acetone powder according to the method of Wang and Kaplan (1954). The acetate buffer supernatant showed only very low specific activity but was largely free of the factors that interfere with the enzyme assay. The Michaelis constants for both substrates were determined, the values were 0·5 mm for NAD and

Production of NADP by immobilized cells with NAD kinase

Biotechnology and Bioengineering, 1982
AbstractBy the radiation‐copolymerization method with polyethylene glycoldimethacrylate (PGD) as a main polymerizable reagent, microbial cells of Brevibacterium ammoniagenes were immobilized with high specific activity of NAD kinase and high mechanical strength.

Calmodulin-dependent NAD kinase of human neutrophils

Archives of Biochemistry and Biophysics, 1985
NAD kinase from human neutrophils has been partially purified by sequential application of Red Agarose, ion-exchange, and gel-filtration chromatography. The enzyme has a broad pH optimum, 7.0-9.5, is strictly dependent upon the presence of Mg2+, and in the absence of calcium exhibits Km values of 0.6 and 0.9 mM for NAD and ATP, respectively. NAD kinase

Immobilization of microbial cells containing NAD‐kinase

Biotechnology and Bioengineering, 1979
AbstractMicrobial cells having NAD‐kinase activity, Brevibacterium ammoniagenes, were immobilized by the radiation‐copolymerization method under low temperature with the activity recovery of more than 80%. Compared to the native microbial cells the immobilized cells were more stable against heat and pH change.

Developmental regulation of NAD+ kinase in Neurospora crassa

Archives of Microbiology, 1982
The specific activity of NAD+ kinase (ATP:NAD+ 2'-phosphotransferase, EC 2.7.1.23) from Neurospora crassa shows sharp peaks when the organism enters a new developmental stage of the asexual life cycle: the peaks are observed during hydration and germination of conidia, at the transition from exponential to stationary growth and at the photostimulated ...
