Enzymatic synthesis and decarboxylation of phosphatidylserine in Tetrahymena pyriformis.
Cell-free extracts of the protozoan Tetrahymena pyriformis have been found to catalyze the following reactions: Phosphatidylethanolamine + L-Serine <==> Phosphatidylserine + Ethanolamine. Phosphatidylserine --> Phosphatidylethanolamine + CO(2) divided by Net: L-Serine --> Ethanolamine + CO(2). The biosynthesis of phosphatidylserine in this organism resembles that found in higher animals. In con...
متن کاملRibosome Synthesis in Tetrahymena Pyriformis
The cellular site of synthesis of ribosomal RNA in Tetrahymena pyriformis was studied by analyzing the purified nuclear and cytoplasmic RNA from cells pulse labeled with uridine-(3)H. The results of studies using zonal centrifugation in sucrose density gradients show that the ribosomal RNA is synthesized in the nucleus as a large precursor molecule sedimenting at 35S. The 35S molecule undergoes...
متن کاملVincristine inhibition of DNA synthesis in Tetrahymena pyriformis.
The effect of vincristine sulfate (VCR)2 on the incorporation of isotopic precursors into protein, RNA, and DNA of the pro tozoan Tetrahymena pyriformis has been studied. DNA synthesis in logartithmically growing cells of T. pyriformi.s was almost completely inhibited by concentrations of VCR which only moderately depressed RNA and protein synthesis. Under ap propriate conditions this selective...
متن کاملRegulation of ribosomal RNA synthesis in Tetrahymena pyriformis.
Ribosomal RNA is synthesized at constant rate during most of the cell cycle in heat-shock synchronized populations of Tetrahymena pyriformis. Early in each macronuclear S-period the rate of synthesis increases abruptly, concomitant with replication of the genes coding for ribosomal RNA. The increase is prevented by inhibitors of DNA replication, added prior to the S-period. Similarly, in cultur...
