Release of thioltransferase from rabbit polymorphonuclear leucocytes by immune complex in vitro and inhibition of the enzyme by chloramphenicol. 1985

M Hatakeyama, and C Lee, and C Chon, and M Hayashi, and T Mizoguchi

Immune complex induced the release of thioltransferase from rabbit peritoneal exudates polymorphonuclear leucocytes in vitro. The release of thioltransferase occurs from viable cells and does not depend on a cytolysis. The catalytic activity of the released enzyme with S-sulfocysteine and glutathione as substrates had a distinct optimum pH at 7.6. On the contrary, opsonized zymosan was not effective as a stimulus for the liberation of thioltransferase from polymorphonuclear leucocytes. Thioltransferase liberated by the stimulation with immune complex was inhibited by chloramphenicol, but not by bacitracin. The inhibition was non-competitive (apparent Ki of 0.2 mM).

D010088 Oxidoreductases The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9) Dehydrogenases,Oxidases,Oxidoreductase,Reductases,Dehydrogenase,Oxidase,Reductase
D011490 Protein Disulfide Reductase (Glutathione) An enzyme that catalyzes the reduction of a protein-disulfide in the presence of glutathione, forming a protein-dithiol. Insulin is one of its substrates. EC 1.8.4.2.

D002701 Chloramphenicol An antibiotic first isolated from cultures of Streptomyces venequelae in 1947 but now produced synthetically. It has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. It acts by interfering with bacterial protein synthesis and is mainly bacteriostatic.
