Rhodanese from Thiobacillus A2: determination of activity by proton nuclear magnetic resonance spectroscopy. 1976

M Silver, and O W Howarth, and D P Kelly

Rhodanese from Thiobacillus A2 was shown by proton nuclear magnetic resonance (NMR) spectroscopy to use dihydrolipoate or dihydrolipoamide as acceptor of the sulphane moiety of thiosulphate with the formation of alpha-lipoate or lipoamide respectively. Correlation is shown between assays of the enzyme activity by NMR spectroscopy and by ultraviolet spectrophotometry.

D008063	Thioctic Acid	An octanoic acid bridged with two sulfurs so that it is sometimes also called a pentanoic acid in some naming schemes. It is biosynthesized by cleavage of LINOLEIC ACID and is a coenzyme of oxoglutarate dehydrogenase (KETOGLUTARATE DEHYDROGENASE COMPLEX). It is used in DIETARY SUPPLEMENTS.

D002474	Cell-Free System	A fractionated cell extract that maintains a biological function. A subcellular fraction isolated by ultracentrifugation or other separation techniques must first be isolated so that a process can be studied free from all of the complex side reactions that occur in a cell. The cell-free system is therefore widely used in cell biology.
