Properties of the Pi-oxygen exchange reaction catalyzed by (Na+,K+)-dependent adenosine triphosphatase.
Properties of the K+-dependent medium Pi .HOH exchange and the K+-dependent p-nitrophenyl phosphatase (PNPPase) reactions of the (Na+,K+)-ATPase were compared. The reactions possess similar monovalent and divalent cation specificities. Pi + HOH exchange was activated by (in decreasing order of effectiveness) NH,+, Rb+, TV, K+, Cs+, and Li+ with M8+ as the divalent cation and MS+, Mn’+, Co2+, Sf...
متن کاملOccurrence and significance of oxygen exchange reactions catalyzed by mitochondrial adenosine triphosphatase preparations.
The capacity of various ATPase preparations from beef heart mitochondria to catalyze exchange of phosphate oxygens with water has been evaluated. Oligomycin-sensitive ATPase preparations retain a capacity for considerable intermediate Pi equilibrium HOH exchange per Pi formed during ATP hydrolysis at relatively high ATP concentration (5 mM). Submitochondrial particles prepared by an ammonia-Sep...
متن کاملInhibition of oxygen evolution in chloroplasts by ferricyanide.
Preincubation of chloroplasts from pea leaves (Pisum sativum L. cv. Kelvedon) with 0.5 millimolar ferricyanide in the dark, caused a parallel inhibition of the rate of rise of the variable fluorescence and the rate of electron transport. Both reactions were inhibited to a similar extent by varying the time of preincubation, the concentration of ferricyanide during preincubation, and by raising ...
متن کاملInhibition of photosynthesis by oxygen in isolated spinach chloroplasts.
The inhibition of photosynthetic CO(2) fixation by O(2), commonly referred to as the Warburg effect, was examined in isolated intact spinach (Spinacia oleracea) chloroplasts. The major characteristics of this effect in isolated chloroplasts are rapid reversibility when O(2) is replaced by N(2), an increased inhibition by O(2) at low concentrations of CO(2) and a decreased effect of O(2) with in...
متن کاملUnivalent reduction of molecular oxygen by spinach chloroplasts on illumination.
Spinach chloroplasts induced the photoreduction of cytochrome c and photooxidation of epinephrine, both of which depended on oxygen and were inhibited by superoxide dismutase. This confirmed the univalent reduction of molecular oxygen in illuminated chloroplasts. In the presence of cytochrome c, hydrogen peroxide formation by chloroplasts was inhibited completely. Rates for the photoreduction o...
