Four cytosolic glutathione S-transferase (GST) classes were isolated and characterized from juvenile winter run Chinook salmon (Oncorhynchus tshawytscha) liver. Two techniques were used: (1) gel electrophoresis/immunoblotting against a polyclonal striped bass GST antibody and (2) high-pressure liquid chromatography (HPLC). Nanospray liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to elucidate peptide sequences and the proteins were identified as pi, theta, mu and alpha, by searching against the NCBI non-redundant database (nrDB). Catalytic activity of the cytosolic GSTs towards 1-chloro-2,4-dinitrobenzene (CDNB) and ethacrynic acid (ETHA) were determined to be 0.3+/-0.05 U/mg cytosolic protein and 0.06+/-0.02 U/mg cytosolic protein, respectively.

D004137 Dinitrochlorobenzene A skin irritant that may cause dermatitis of both primary and allergic types. Contact sensitization with DNCB has been used as a measure of cellular immunity. DNCB is also used as a reagent for the detection and determination of pyridine compounds. 1-Chloro-2,4-Dinitrobenzene,2,4-Dinitrochlorobenzene,Benzene, 1-Chloro-2,4-Dinitro-,Chlorodinitrobenzene,DNCB,1 Chloro 2,4 Dinitrobenzene,2,4 Dinitrochlorobenzene
D004976 Ethacrynic Acid A compound that inhibits symport of sodium, potassium, and chloride primarily in the ascending limb of Henle, but also in the proximal and distal tubules. This pharmacological action results in excretion of these ions, increased urinary output, and reduction in extracellular fluid. This compound has been classified as a loop or high ceiling diuretic.

D005982 Glutathione Transferase A transferase that catalyzes the addition of aliphatic, aromatic, or heterocyclic FREE RADICALS as well as EPOXIDES and arene oxides to GLUTATHIONE. Addition takes place at the SULFUR. It also catalyzes the reduction of polyol nitrate by glutathione to polyol and nitrite.
