Mitochondrial DNA in Tetrahymena pyriformis

Experimental Cell Research, 1969
Abstract Contrary to the reports in the literature, no satellite DNA bands were found in DNA isolated from Tetrahymena pyriformis strains 6III, HSM, ST, or GL; all of the DNA from a given strain had a single buoyant density in CsCl. A technique for resolving 2 DNAs of only slightly different buoyant density using 2 different radioactive labels is ...

The accumulation of cholesterol by Tetrahymena pyriformis

Experimental Cell Research, 1964
Abstract Extensive accumulation of 14 C-4-cholesterol by Tetrahymena pyriformis suspended in a non-growth medium at 29 °C was observed over a 4-hr period. At lower temperatures (13–19 °C) three separate phases of cholesterol uptake could be distinguished: ( a ) an initial, rapid, temperature independent phase, ( b ) a lag phase, and ( c ) a ...

Isocitrate dehydrogenase of Tetrahymena pyriformis

Molecular and Cellular Biochemistry, 1977
We have studied the isocitrate dehydrogenase of Tetrahymena pyriformis. This enzyme is able to utilize both NAD and NADP, but kinetic studies suggest that the enzymatic activity with NAD is not of physiological signifance. Some of the factors that might regualte the NADP-dependent isocitrate dehydrogenase were also studied.

Chromatin Replication in Tetrahymena pyriformis

1981
Publisher Summary The chapter discusses the investigation of chromatin replication in Tetrahymena provided some unexpected evidence in favor of an altered conformation of chromatin in the immediate area of the replication fork, which would be consistent with the involvement of fixed structural entities at the fork region.

Serine biosynthesis in Tetrahymena pyriformis S

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971
Abstract 1. 1. Glycine transhydroxymethylase and threonine aldolase function in the formation of serine in Tetrahymena pyriformis S. 2. 2. Both the phosphorylated and non-phosphorylated pathways of serine biosynthesis from 3-phosphoglycerate are also operative. 3. 3. Tricarboxylic acid cycle intermediates also serve as serine precursors
