Free Amino Acids in Serine-Antagonized Cells of Tetrahymena pyriformis.
Wragg, June B. (Agricultural Research Service, Beltsville, Md.), Howard Reynolds, and Michael J. Pelczar, Jr. Free amino acids in serine-antagonized cells of Tetrahymena pyriformis. J. Bacteriol. 90:748-754. 1965.-Growth inhibition of Tetrahymena pyriformis by l-serine in a chemically defined medium was reversed by l-arginine in a manner which resembled competitive antagonism. Composition of th...
متن کاملFree and nonprotein amino acids of Tetrahymena pyriformis.
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 کاملCell Division and Dna Synthesis in Tetrahymena Pyriformis Deprived of Essential Amino Acids
The question of amino acid requirements for DNA synthesis and cell division has been studied in Tetrahymena pyriformis by depriving cells of histidine and tryptophan at defined stages in the interdivision interval. Deprivation any time before DNA synthesis does not prevent the initiation of such synthesis but completely inhibits the following division and limits the increase in DNA, as measured...
متن کاملFatty 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 کاملThe metabolism of cyclopropane fatty acids by Tetrahymena pyriformis.
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 ...
