1. The steady-state rate of hydrolysis of 2,4-dinitrophenyl phosphate catalysed by Escherichia coli phosphatase is identical with that of 4-nitrophenyl phosphate over the pH range 5.5-8.5. 2. The increase in the rate of the enzyme-catalysed decomposition of nitrophenyl phosphates in the presence of tris at pH8.1 and 5.9 is consistent with the hypothesis that tris increases the rate of decomposi...

Two strains of lymphoblasts, the malignant MB VIA and the nonmalignant MB HI ' , both derived by continuous subculture from an explant of a mouse lymphosarcoma, were cultured in large amounts. The respiration, anaerobic and aerobic glycolysis of the cells were measured, and the effects of ~, 4-dinitrophenol and the tumor-inhibitory compound 4(4'-dimethylaminostyryl)quinoline on the latter proce...

Purified preparations of F1-ATPase (ATP phosphohydrolase; EC 3.6.1.3) isolated from yeast mitochondria catalyze the reaction of oleoylphosphate with ADP to yield ATP and oleic acid. Formation of ATP is specifically inhibited by the F1-ATPase inhibitor 1799 and by dinitrophenol. In the presence of F1, dinitrophenol "uncouples" the synthase reaction by causing rapid hydrolysis of oleoylphosphate ...

Linoleic acid and monomethyldecenylsuccinic acid were tested as uncoupling agents for energy linked functions of corn mitochondria. 2,4-dinitrophenol was used as a standard for comparison. Both compounds uncoupled oxidative phosphorylation, released oligomycin-blocked respiration, and accelerated adenosine triphosphatase. Linoleic acid uncoupled calcium-activated phosphate accumulation and the ...

Molecular imprinted polymers (MIP) are considered one of the most promising selective and novel separation methods for removal phenolic compound in wastewater treatment. MIP are crosslinked polymeric materials that exhibit high binding capacity and selectivity towards a target molecule (template), purposely present during the synthesis process. In this work MIP were prepared in a bulk polymeriz...

In the present study, ultrasound-assisted Fe3O4@TiO2 magnetic nanocomposite was employed to catalytic oxidation of 2,4-Dinitrophenol. The catalyst features were characterised by SEM, TEM, XRD, BET, FTIR, VSM, DLS and TGA techniques. effect operational parameters i.e. pH, amount, 2,4-Dinitrophenol concentration ultrasound power on DNP removal examined optimised in terms sono-catalytic degradatio...

Within ten days of incubation, freshly ripe tomato fruits (Ibadan local variety) obtained from a local market in Ile-Ife, Osun State, Nigeria had completely deteriorated and proteins which possessed cellulolytic activity were released. The enzyme was partially purified by a combination of ammonium sulphate precipitation, molecular exclusion chromatography and ion-exchange chromatography. The en...
