Ferredoxin biosynthesis in Euglena gracilis

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1976
Analysis of ferredoxin content in cultures of Euglena gracilis grown in the presence of selective antibiotic inhibitors of protein synthesis resulted in the following conclusions: 1. Ferredoxin is synthesized from cytoplasmic (80s-type) ribosomes; cycloheximide, a potent inhibitor of 80s translation completely abolished the synthesis, while the ...

Subunit organization of Euglena chromatin

Biochemical and Biophysical Research Communications, 1980
Abstract Digestion of Euglena nuclei or extracted chromatin with micrococcal nuclease results in the identification of a repeating structure. The DNA repeat size, analyzed on agarose and polyacrylamide gels, is found to be 225±13 base pairs. DNase I digestion produces a serie of fragments multiples of roughly 10 bases.

C2 metabolism in Euglena

2017
Euglenoids are able to assimilate fatty acids and alcohols with various carbon-chain lengths, and ethanol is known to be one of the best carbon sources to support the growth of Euglena gracilis. Ethanol is first oxidized to acetate by the sequential reactions of alcohol dehydrogenase and acetaldehyde dehydrogenase in the mitochondria, and then ...

A Euglena gracilis zinc endonuclease

Biochemistry, 1993
A 26-kDa endonuclease has been purified to homogeneity from zinc-sufficient Euglena gracilis. The protein binds to single-stranded DNA with a higher affinity than to double-stranded DNA, but it exhibits nucleolytic activity toward both. Thus, it converts supercoiled plasmid pBR322 DNA into the linear form, a property characteristic of endonucleases ...

Properties of selectively starved Euglena

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1967
Abstract It has been shown that starving Euglena for an essential nutrient causes it to reduce its nuclear and plastid complements by one-half. If pressed by extreme deprivation of the nutrient, the cell is finally pushed to discard its plastid complement which is gratuitous in the heterotrophic medium in which the cell is growing.

Flagellar waveform reversal in Euglena

Experimental Cell Research, 1980
Abstract Films taken during experiments on the electrical control of flagellar motion in Euglena and of control by microinjection were analysed for the occurrence of the reversal reaction of the flagellar waveform. In all cases it was found that an induced decrease in flagellar frequency is accompanied by an increased fraction of the cells showing ...

Respiratory cytochromes of Euglena gracilis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1969
Abstract 1. 1. Difference spectra of whole cells and of a particulate fraction of a streptomycin-bleached strain of Euglena gracilis showed the presence of a b -type cytochrome, cytochrome b (561 Euglena), and an a -type cytochrome, cytochrome a -type (609 Euglena). The cytochromes were characterized by pyridine hemochromogen formation and

[36] Euglena Cytochromes

1971
Publisher Summary Several cytochromes can be isolated from Euglena species, for example, c 552 , c -type 556, b -type 561 (558 and 563), and a -type 605. Only cytochrome c 552 has been highly purified and fully characterized. In the course of purification procedure of cytochrome c 552 , wild-type strains of Euglena gracilis are grown in

Laminarase of Euglena gracilis

Science, 1960
An enzyme in extracts of the protistan Euglena gracilis splits the polysaccharide laminarin (β-1:3-glucosan). Its optimal p H is 5.0, and it is activated by Mn ++ ions.
