Cells save their energy during nitrogen starvation by selective autophagy of ribosomes and degradation of RNA to ribonucleotides and nucleosides. Nucleosides are hydrolyzed by nucleoside N‐ribohydrolases (nucleosidases, NRHs). Subclass I of NRHs preferentially hydrolyzes the purine ribosides while subclass II is more active towards uridine and xanthosine. Here, we performed a crystallographic and...
Polyamines such as spermidine and spermine are essential regulators of cell growth, differentiation, maintenance of ion balance and abiotic stress tolerance. Their levels are controlled by the spermidine/spermine N1‐acetyltransferase (SSAT) via acetylation to promote either their degradation or export outside the cell as shown in mammals. Plant genomes contain at least one gene coding for SSAT (also...
The article describes the algorithm created in the interactive environment Matlab and provides the detection of two sleep stages, specifically NREM1 and NREM3/4. One of possible methods is to split the signal into 30 seconds segments. These are later divided by means of adaptive segmentation. Subsequently the properties of individual segments are described (using Hjorth parameters and amplitude) and...
