Incorporation of labelled amino acids by nuclei isolated from Euglena gracilis

June R. Aprille, D. E. Buetow

Research output: Contribution to journalArticlepeer-review


Nuclei isolated from the lower eukaryote, Euglena gracilis, incorporate labelled amino acids into hot-TCA-insoluble material under conditions of incubation similar to those used for higher eukaryotes. Optimal temperature for amino acid incorporation by Euglena nucleic is 25° to 30°C. Optimal pH is 5.0. ATP stimulates incorporation only to a small extent. Evidence is presented that the product synthesized is protein.
