Plant Physiology
Puccinia striiformis f. sp. tritici (Pst) secretes effector proteins that enter plant cells to manipulate host immune processes. In this report we present an important Pst effector, Pst03724, whose mRNA expression level increases during Pst infection of ...

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, 1967The 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.

Developmental regulation of NAD+ kinase in Neurospora crassa
Archives of Microbiology, 1982The 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 ...

Developmental Ontogeny of NAD+ Kinase in the Rat Conceptus
Toxicology and Applied Pharmacology, 2001The ubiquitous NAD+ kinase (NADK) is the only known enzyme to catalyze formation of NADP+ from NAD+. The capacity to maintain an adequate supply of NADP(H) has important implications for development because of its requirement as a cofactor and electron donor in biosynthesis and detoxication reactions.

PROPERTIES OF RAT BRAIN NAD‐KINASE
Journal of Neurochemistry, 1970Abstract— 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

Calmodulin-dependent NAD kinase of human neutrophils
Archives of Biochemistry and Biophysics, 1985NAD 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

Structural and Functional Characterization of Human NAD Kinase
Biochemical and Biophysical Research Communications, 2001NADP is essential for biosynthetic pathways, energy, and signal transduction. Its synthesis is catalyzed by NAD kinase. Very little is known about the structure, function, and regulation of this enzyme from multicellular organisms. We identified a human NAD kinase cDNA and the corresponding gene using available database information.

Immobilization of microbial cells containing NAD‐kinase
Biotechnology and Bioengineering, 1979AbstractMicrobial 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.
