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 ...

Euglena gracilis cytochrome 558
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972Abstract Euglena gracilis contains both the classical cytochrome f (cytochrome c 552 ) found in algae and plants, and an atypical cytochrome 558, which has covalently bound heme. We report here some of the chemical and physical properties of cytochrome 558, including amino acid composition, molecular size, and spectral properties.

Oxidative metabolism of Euglena
Archives of Biochemistry and Biophysics, 1953Abstract The metabolic behavior of intact and disrupted Euglena cells is consistent with the hypothesis that oxidative metabolism of Euglena occurs via the Krebs cycle, and that impermeability of the Euglena cell membrane to many organic acid anions limits the availability of such compounds as carbon and energy sources for intact Euglena .

Nuclear transformation of the versatile microalga Euglena gracilis
Algal Research, 2019Euglena gracilis is a unicellular microalga studied for the production of nutraceuticals, cosmeceuticals and biofuel. Full exploitation of the organism requires the development of genetic engineering tools including a method for obtaining genetically ...

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.

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.

Fully Deuterated Euglena gracilis
Science, 1964Euglena gracilis has been grown in 99.4 percent D 2 O on fully deuterated substrates. It is the first organism with distinct animal characteristics in which at least 99 percent of the hydrogen normally present has been replaced by deuterium.

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.
