Enzyme Systems in Tetrahymena Geleii S
نویسنده
چکیده
The rates of activity of the dehydrogenase systems in Tetrahymena, which are concerned with carbohydrate oxidation, in descending order of activity are: lactic > isocitric > succinic = glucose > glucose-6-phosphate = 6-phosphogluconic = malic > glutamic = cytochrome linked alpha-glycerophosphate dehydrogenase. No evidence was obtained to indicate the presence of DPN linked alpha-glycerophosphate dehydrogenase.

Enzyme Systems in Tetrahymena Geleii S* I. Anaerobic Dehydrogenases Concerned with Carbohydrate Oxidation By
In view of the present increased interest in the metabolism of the ciliate, Tetrahymena gdeii, an investigation of the relative activity of the anaerobic dehydrogenases which have a direct role in carbohydrate oxidation was undertaken as the first phase of a general survey of enzymatic activity in this organism. The presence in the ciliate of the dehydrogenases active in the tricarboxylic acid ...
متن کاملUtilization of acetate by Tetrahymena geleii (S).
Tetrahymena geleii (S) (Colpidium camp&m) is a ciliated protozoan which has been shown to be capable of synthesizing lipides from protein at an unusually high rate (1, 2). The next obvious step in studies concerned with the metabolism of this organism, therefore, seemed to be a search for the compound, or compounds, serving as precursor of the lipide material. Acetate is known to play a key r&e...
متن کاملGrowth studies on Tetrahymena geleii H.
l’ctmhymena g&ii II, a holotrichous protozoan, was isolated as a bacteria-free culture in 1931 by Dr. Alford Hetherington at Pacific Grove, California. The culture of the ciliate employed in the present studies was obtained in 1945 through the courtesy of Dr. George W. Kidder, who had received a culture from Dr. R. H. Hall in 1938 (2). Hetherington named this microorganism Colpidium campylum, b...
متن کاملThe amino acid composition and nitrogen metabolism of Tetrahymena geleii.
The nitrogen composition and metabolism of the typical animal microorganisms are relatively unknown. This is true largely because of the past unavailability of the Protozoa either in pure culture or in synthetic media. The ciliated protozoan, Tetrahymena geleii, is unique in that it has been available in pure culture for some time and recently (1949) it has been grown in synthetic medium (2). I...
متن کاملThe Effect of Urethane on the Consumption of Oxygen and the Rate of Cell Division in the Ciliate Tetrahymena Geleii
1. The inhibition of oxygen consumption produced by a series of concentrations of ethyl carbamate has been measured in the protozoan Tetrahymena geleii. 2. The relation found between the narcotic concentration and its effect on respiration leads to the conclusion that urethane has two distinct modes of action in this cell. The respiratory data can be accurately predicted by assuming that the in...
