A microsomal oxidation which is highly inducible by ethanol. p-Nitrophenol is widely employed as a substrate for the study of the glucuronide and sulfate conjugation pathways. However, in perfused livers from ethanol-treated rats, p-nitrophenol was rapidly metabolized to 4-nitrocatechol. The 4-nit...

β-Xylosidase activity was measured spectrophotometrically by the release of p-nitrophenol (pNP; ε410 = 15,200 M−1 cm−1) from p-nitrophenyl β-d-xylopyranoside (pNPX). The standard reaction mixture contained 3.5 mM pNPX, 50 mM sodium acetate buffer (pH 5.0), and 0.1...
Although the insecticides parathion and diazinon are well distributed throughout the body and extensively bind to both plasma and tissue proteins, they are both rapidly cleared from the body primarily in the urine as degradation metabolites of the parent compounds [i.e., p-nitrophenol, 2-isopropyl...
After completion of the incubation period, 100 mM sodium carbonate solution was added to the reaction mixture and the concentration of p-nitrophenol was quantified by measuring the absorbance at 420 nm. To assay activity towards recalcitrant substrates, the incubation time was extended from 30...
α-l-Rhamnosidase activity in cell-free extracts was measured using the artificial substratep-nitrophenyl-α-l-rhamnopyranoside (pNPR). The release ofp-nitrophenol was measured spectrophotometrically at 400 nm. The assay was performed in 96-well microtitre plates in final volumes of 250 μl using...
aThe activity is expressed as nmol p-nitrophenol/min/ml. Values are average of at least three independent experiments each with three replicates. '±' indicates standard error of means (SEM). Growth and end product analysis. To further investigate CcpA, and GlnR's role in pneumococcal ...
