    Notes: We have demonstrated that InP:Fe photoconductive detectors are sensitive to radiation between 20 and 3000 eV. Within experimental error the measured response is flat in this energy range, in agreement with theory. This property, coupled with the simplicity and high speed (full width at one half maximum of less than 200 ps) of these devices, makes them very interesting for the measurement of pulsed vacuum ultraviolet and x-ray radiation and the total instantaneous integrated radiative power emitted from a pulsed source. Low fidelity response can occur in these devices for excitation times that are many times longer than the primary response time of the detector.

    Photoconductor x/γ-ray detectors and x-ray bolometers (1986)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Photoconductors are very promising x/γ-ray detectors and x-ray bolometers for pulsed x/γ-ray measurements. They are fast, sensitive, and theoretically flat in spectral response for low energy x rays. We report our tests of InP:Fe, GaAs, and GaAs:Cr, both neutron damaged and undamaged, at Nova laser, Febetrons, and electron linear accelerators. The temporal and spectral responses are discussed.

    Regulation in tobacco callus of enzyme activities of the nicotine pathway (1986)
    Springer

    Topics: Biology
    Notes: Abstract Nicotine synthesis was stimulated by reduction of the medium auxin concentration (induction medium) in callus tissue originating from Nicotiana tabacum cv. Samsun. The enzyme activities of the route ornithine to methylpyrroline, which are those of ornithine decarboxylase, putrescine methyltransferase and methylputrescine oxidase, were determined during callus growth in the induction medium and as a control under non-nicotine-stimulating conditions (growth medium). The enzymes were assayed by high-performance liquid chromatography. Whereas the activities of ornithine decarboxylase were very similar under nicotine-stimulating and non-stimulating conditions, those of putrescine methyltransferase and methyl-putrescine oxidase increased strongly in the induction medium. In addition, the pools of putrescine and methylputrescine were determined throughout the callus growth cycle. Both sets of data strongly confirm the supposition that putrescine methyl-transferase is the enzyme under stringent control for nicotine biosynthesis, whereas the subsequent methylputrescine oxidase is co-regulated, although less stringently.

    The pyridine-nucleotide cycle in tobacco (1986)

    Notes: Abstract In order to elucidate the NAD-recycling pathway the following enzyme activities have been characterized in different tobacco tissues and in tomato root: NAD pyrophosphatase, nicotinamide mononucleotide (NMN)/nicotinic acid mononucleotide (NaMN) glycohydrolases, nicotinamidase and nicotinic acid phosphoribosyltransferase. The investigations were performed with protein extracts purified by gel filtration and enzymatic activities were determined by high-performance liquid chromatography methods. The kinetic parameters of the different enzymes from tobacco root and their specificity are reported. The data are in favor of the so-called pyridine-nucleotide cycle VI (NAD→NMN→nicotinamide→nicotinic acid→NaMN→nicotinic acid adenine dinucleotide→NAD). In the nicotine-producing tobacco root a further direct route leading from NaMN to nicotinic acid is proposed. These data are reconciled with the assumption that it is nicotinic acid which is provided by the pyridine-nucleotide cycle for the synthesis of nicotine.

    Regulation in tobacco callus of enzyme activities of the nicotine pathway (1986)

    Notes: Abstract In tobacco callus, the induction of nicotine synthesis, which stimulates enzyme activities of the ornithine-methylpyrroline route (see the preceding paper), also leads to marked changes in the enzyme activities of the pyridine-nucleotide cycle. This cycle provides the metabolite (probably nicotinic acid) for condensation with methylpyrroline to produce nicotine. The activities of eight enzymes of the pyridine-nucleotide cycle and of quinolinic-acid phosphoribosyltransferase, the anaplerotic enzyme, were determined by high-performance liquid chromatography assays. The distinct changes of their activities upon induction of nicotine synthesis lead to the following conclusions: i) nicotinic acid is the relevant metabolite which is provided by the pyridine-nucleotide cycle and consumed for nicotine synthesis. ii) The enhancement of the nicotinic-acid pool arises in two ways, by synthesis of NAD and degradation via nicotinamide mononucleotide and by a direct route from nicotinic-acid mononucleotide (NaMN) which is degraded by a glycohydrolase with a rather high K m value. Such a K m value prevents the complete depletion of the NaMN pool.
