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.

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 ...

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 .

Occurrence of norspermine in Euglena gracilis
Biochemical and Biophysical Research Communications, 1978Summary The tetraamine occurring in Euglena gracilis , previously believed to be spermine, is shown to be norspermine [N, N′-bis (3-aminopropyl)-1,3-diaminopropane]. Proof of identity was established by HPLC, HPCC and mass spectrometric investigations.

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.

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.

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 ...

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 ...

A Euglena gracilis zinc endonuclease
Biochemistry, 1993A 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 ...
