Journal ArticleDOI
Localization of polyphosphates in Saccharomyces fragilis, as revealed by 4′,6-diamidino-2-phenylindole fluorescence
TL;DR: The results suggest a momentary interaction of diamidinophenylindole with polyphosphate, localized outside the plasma membrane, followed by a slow penetration of the dye into the cells, yielding increased fluorescence at 456 nm by interaction of the dyed with e.g., nucleic acids.
Journal ArticleDOI
Photodynamic effects of protoporphyrin on human erythrocytes. Nature of the cross-linking of membrane proteins.
TL;DR: Quantitative data and consideration of the reaction mechanisms of photodynamic oxidation of amino acids make it highly probable that an oxidation product of histidine rather than of tyrosine or tryptophan is involved in the cross-linking reaction, via a nucleophilic addition by free amino groups.
Journal ArticleDOI
Transport and transport-associated phosphorylation of 2-deoxy-d-glucose in yeast
TL;DR: This work has shown that there is not a transport of free deoxyglucose into the cells followed by intracellular phosphorylation by the hexokinase-ATP system, but thatosphorylation of deoxy glucose is associated with transport (followed by partial intrACEllular hydrolysis).
Journal ArticleDOI
Protein damage, induced by small amounts of photodynamically generated singlet oxygen or hydroxyl radicals
TL;DR: The results indicate that limited protein oxidation may have a pronounced influence on several properties of the protein, although the effects vary, however, with varying proteins and with the oxidizing species.
Journal ArticleDOI
Inhibition of enzymes and oxidative damage of red blood cells induced by t-butylhydroperoxide-derived radicals.
TL;DR: Experimental results indicate that tBuO.
