“…Because TeA interrupts PS 2 electron flow and ATP synthesis, it is regarded as an inhibitor of redox energy conservation and therefore also is expected to increase the energization levels in thylakoid, which can result in a large generation of ROS (Chen et al, 2010). Barr et al (1988) observed very efficient PET inhibition in PS 2 of spinach chloroplasts by the platelet activating factor 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine, a phospholipid, which is an ether analogue of phosphatidylcholine. Application of 2.8 to 3.5 μg cm -3 of this compound resulted in > 90% PET inhibition.…”

visible in Fig. 1a (full line) and belongs to the intermediate D  , i.e. to the tyrosine radical in the 161th position of D 2 protein on the donor side of PS 2 (Debus et al., 1988a) and (ii) EPR signal II very fast (g = 2.0046, B pp = 1.9 mT) which is observable as an increase of signal II in light (Fig. 1a, difference between the dashed and full lines). This signal belongs to the intermediate Z  , i.e. to the tyrosine radical in the 161th position of D 1 protein (Debus et al., 1988b) which is also situated on the donor side of PS 2. Further EPR signal is associated with cation-radical of chlorophyll (Chl) a dimer situated in the core of PS 1 (Hoff, 1979).

The secreted phosphatase activities of two trypanosomatid parasites were characterized and compared with supernatants of living cells. The plant parasite Phytomonas françai and the phytophagous hemipteran parasite Herpetomonas sp. hydrolyzed p-nitrophenylphosphate at a rate of 15.54 and 6.51 nmol Pi/mg of protein per min, respectively. Sodium orthovanadate (N(a)VO(3)) and sodium fluoride (NaF) decreased the phosphatase activities. The phosphatase activity of P. françai was drastically diminished (73% inhibition) in the presence of sodium tartrate, whereas the phosphatase activity of Herpetomonas sp. was inhibited by 23%. Cytochemical analysis showed the localization of these enzymes on the external surface and in the flagellar pocket of the two trypanosomatids. Sodium tartrate inhibited this reaction, confirming the biochemical data. Platelet-activating factor modulated the phosphatase activities, inhibiting P. françai activity and stimulating Herpetomonas sp. phosphatase activity.
