We have used a rat glutathione S-transferase P (GST-P) complementary DNA as a probe to screen a human placenta complementary DNA library constructed in the lambda gt11 vector. One of the positive clones contained the complete coding region (630 base pair) and the entire 3'-noncoding region (78 base pair) of the putative human glutathione S-transferase pi (GST-pi) subunit mRNA. From the nucleoti...
Three major forms of cytosolic glutathione S-transferase (designated F1, F2, and F3 transferases according to increasing isoelectric points) were purified to homogeneity from liver of DBA/2J mice, primarily by CM-cellulose and hydroxylapatite chromatography. The purified enzymes were shown to have specific activities of 104, 281, and 143 units/mg, respectively, when assayed with 1 m~ each of l-...
Studies on T H E Mode of Action of Diphtheria Toxin* Vi. Site of the Action of Toxin in Living Cells
I t has been shown in previous communications that, in the presence of the specific cofactor nicotinamide adenine dinucleotide (NAD), diphtheria toxin inhibits the transfer of amino acids from aminoacyl-tRNA to the growing polypeptide chains on the ribosomes in cell-free extracts from mammalian cells (1). Although bacterial cell extracts axe completely insensitive to inhibition (1), toxin and N...
Human liver glutathione S-transferases (GSH S-transferases) were fractionated into cationic and anionic proteins. During fractionation with (NH4)2SO4 the anionic GSH S-transferases are concentrated in the 65%-saturated-(NH4)2SO4 fraction, whereas the cationic GSH S-transferases separate in the 80%-saturated-(NH4)2SO4 fraction. From the 65%-saturated-(NH4)2SO4 fraction two new anionic GSH S-tran...
