Title: | The effect of anoxia on PolyP content of Phycomyces blakesleeanus mycelium studied by<sup>31</sup>P NMR spectroscopy | Authors: | Zakrzewska, Joanna Žižić, Milan Živić, Miroslav |
Keywords: | 31 P NMR;Anoxia;Phycomyces;Poly phosphates | Issue Date: | 1-Jan-2005 | Journal: | Annals of the New York Academy of Sciences | Abstract: | The effect of anoxia and the respiratory chain inhibitors azide and cyanide on the polyphosphate content of Phycomyces was studied by in vivo 31P NMR spectroscopy. Anoxia was manifested by a decrease of core polyphosphates (PPi) and increase of intracellular inorganic phosphate (Pi) signal. Normalized changes in PPi/P i ratio between control and nitrogen-purged mycelia suggest that the sensitivity to anoxia differs with growth phases. Azide acts in the same way as anoxia, by decreasing the PPi/Pi ratio, while cyanide causes an increase of the PPi/Pi ratio. © 2005 New York Academy of Sciences. |
