The metabolism of cyclopropane fatty acids by Tetrahymena pyriformis.
نویسندگان
چکیده
Cyclopropane fatty acids are readily metabolized by whole cells of Tetrahymena pyriformis when the fatty acids are presented either as components of intact Escherichia coli cells or as free fatty acids added to the medium. cis-ll,lZ[methylene-14C]Methyleneoctadecanoic acid was degraded with the production of 14COz by whole T. pyriformis cells or a particulate fraction derived from them. In the presence of malonate, [W4C]acetate was formed. A pathway for degradation of the cyclopropane fatty acids, requiring only minor modification of the usual /3 oxidation pathway, is proposed.

Fatty acids of mitochondrial membranes from Tetrahymena pyriformis.
We have examined the fatty acid composition of the mitochondrial membranes in three strains of Tetrahymena pyriformis. All three had similar components and exhibited large amounts of unsaturated fatty acids. The cytoplasmic mutant, CA-10, which has a slower growth rate and unusual membrane morphology, had a slightly higher amount of iso-acids but was otherwise similar to the other strains in fa...
متن کاملNalidixic acid and macromolecular metabolism in Tetrahymena pyriformis: effects on protein synthesis.
A study on the effect of nalidixic acid on macromolecular metabolism, particularly of protein, in Tetrahymena pyriformis was performed. It was shown that the compound is a potent inhibitor of deoxyribonucleic acid, ribonucleic acid, and protein synthesis for this organism. A conspicuous breakdown of polysomes, accompanied by the accumulation of 80S ribosomes, occurred in cells incubated for 10 ...
متن کاملPositional distribution of fatty acids in the glycerophospholipids of Tetrahymena pyriformis.
The positional distributions of the fatty acids in the major glycerophospholipids of Tetrahymena pyriformis W were analyzed. A comparison was made of the acyl distributions in normal and ergosterol-grown cells. It was assumed that the positional arrangement of fatty acids would serve as an indicator of acyltransferase enzyme specificity. The acyltransferases in this protozoan have substrate spe...

In a previous study (l), the composition of total cellular amino acids of the ciliated protozoan, Tetrahymena pyriformis (formerly, T. geleii), was presented together with other pertinent data concerning the nitrogen metabolism of this organism. The present investigation was undertaken to obtain information on the free and nonprotein amino acids of this protozoan cell, inasmuch as the nonprotei...
متن کامل15N investigation into the effect of a pollutant on the nitrogen metabolism of Tetrahymena pyriformis as a model for environmental medical research.
A pilot study was performed to examine the potential of stable isotope techniques for monitoring the impact of a harmful substance on the cellular nitrogen metabolism in the ciliate species Tetrahymena pyriformis. After identical cultivation periods of control cells and toluene-exposed cells in a defined culture medium enriched with [guanidino-15N2]l-arginine, a number of nitrogen-containing po...
