RNA transcript processing is an important stage in the gene expression pathway of all organisms and is subject to various mechanisms of control that influence the final levels of gene products. RNA processing involves events such as nuclease-mediated cleavage, removal of intervening sequences referred to as introns and modifications to RNA structure ...

Heteroxanthin in Euglena gracilis
Archiv f�r Mikrobiologie, 19731. From a large scale preparation of Euglena gracilis, strain Z, besides the acetylenic pigments diatoxanthin and diadinoxanthin and the allene neoxanthin, an additional acetylenic xanthophyll has been isolated. 2. Mass and IR spectra and chemical reactions showed typical patterns of heteroxanthin from Vaucheria. 3.

Induction of fumarase in resting Euglena
Biochimica et Biophysica Acta (BBA) - General Subjects, 1982Exposure of dark-grown resting (carbon deficient) Euglena to light, ethanol or malate produced a transient increase in the specific activity of fumarase. Fumarase levels decreased 8-12 h after the start of induction and this decrease could not be prevented by additional inducer.

Thiamin uptake in Euglena gracilis
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1987Thiamin uptake has been investigated in Euglena gracilis Z. This protozoon possessed an active transport system for thiamin with a Km value of 17 nM and a Vmax value of 7.8 pmol per 10(6) cells per min. Thiamin uptake was dependent on pH and temperature, but not on exogenous glucose as an energy source.

Degradation of Paramylon by Euglena gracilis
The Journal of Protozoology, 1968SYNOPSIS. Protozoa of the order Euglenida contain a polysaccharide storage product, paramylon, composed of 1, 3‐linked glucose molecules arranged into an extremely resistant granule. An enzyme was purified from the soluble phase of Euglena gracilis which would degrade this polysaccharide to single glucose residues, providing the integrity of the ...

Ribonuclease of Euglena gracilis
Science, 1960An enzyme in extracts of Euglena gracilis splits both purine and pyrimidine internucleotide bonds of ribonucleic acid. Its p H optimum is at 4.5; it is very heat-labile and is rather insensitive to inhibition by metal ions or sulfhydryl group reagents.

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 ...

Flagellar waveform reversal in Euglena
Experimental Cell Research, 1980Abstract 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 ...

Protein Targeting to the Plastid of Euglena
2017The lateral transfer of photosynthesis between kingdoms through endosymbiosis is among the most spectacular examples of evolutionary innovation. Euglena, which acquired a chloroplast indirectly through an endosymbiosis with a green alga, represents such an example.
