Effects of multivalent cations on cell wall-associated Acid phosphatase activity.
Primary cell walls, free from cytoplasmic contamination were prepared from corn (Zea mays L.) roots and potato (Solanum tuberosum) tubers. After EDTA treatment, the bound acid phosphatase activities were measured in the presence of various multivalent cations. Under the conditions of minimized Donnan effect and at pH 4.2, the bound enzyme activity of potato tuber cell walls (PCW) was stimulated...
متن کاملEcto-phosphatase activity on the cell surface of Crithidia deanei.
In the present work we have partially characterized an ecto-phosphatase activity in Crithidia deanei, using viable parasites. This enzyme hydrolyzed p-nitrophenylphosphate at a rate of 3.55 +/- 0.47 nmol Pi/h x 10(8) cells. The dependence on p-NPP concentration shows a normal Michaelis-Menten kinetics for this phosphatase activity and the value of the apparent Km for p-NPP was 5.35 +/- 0.89 mM....
متن کاملThe effect of Dendrostellera lessertii on the cell membrane redistribution of alkalinee phosphatase
Several mammalian enzymes are anchored to the outer surface of plasma membrane by a covalently attached glycosyl-phosphatidylinisitol (GPI) structure. These include acetylcholinesterase, alkalinee phosphatase and 5´-nucleotidase. Recently, it has been reported that these membrane enzymes can be solubilized into the serum by GPI-dependent PLD, under various medical disturbances such as cancer an...

متن کاملThe Effects of Candida Albicans Cell Wall Protein Fraction on Dendritic Cell Maturation
Back ground: Candida albicans is a member of the normal human microflora. C. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in C. albicans interaction with the host immune system. Major components of C. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...
