On the Prediction of In Vitro Arginine Glycation of Short Peptides Using Artificial Neural Networks

open access: yesSensors, 2022
One of the hallmarks of diabetes is an increased modification of cellular proteins. The most prominent type of modification stems from the reaction of methylglyoxal with arginine and lysine residues, leading to structural and functional impairments of ...

Urinary felinine excretion in intact male cats is increased by dietary cystine [PDF]

open access: yes, 2008
Felinine is a branched-chain sulfur amino acid present in the urine of certain Felidae, including domestic cats. The objective of the present study was to determine if additional cystine and/or dietary N would increase felinine and N-acetylfelinine ...

Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

open access: yesFEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...

Arginine starvation kills tumor cells through aspartate exhaustion and mitochondrial dysfunction

open access: yesCommunications Biology, 2018
Defective arginine synthesis, due to the silencing of argininosuccinate synthase 1 (ASS1), is a common metabolic vulnerability in cancer, known as arginine auxotrophy.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

open access: yesFEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

On the Species Specificity of Acceptor RNA and Attachment Enzymes [PDF]

open access: yes, 1961
One of the steps in protein biosynthesis appears to be the attachment of each amino acid to a specific acceptor (SRNA) molecule. According to the adaptor hypothesis, each SRNA molecule would then fit to a specific complementary base sequence on a linear ...

Physiological implications of arginine metabolism in plants

open access: yesFrontiers in Plant Science, 2015
Nitrogen is a limiting resource for plant growth in most terrestrial habitats since large amounts of nitrogen are needed to synthesize nucleic acids and proteins.

Interplay between RNA‐protein interactions and RNA structures in gene regulation

open access: yesFEBS Open Bio, EarlyView.
Methodological advances in mapping transcriptome‐wide RNA‐protein interactions and RNA structures have started to uncover the potential of RNP conformations in gene regulation. Competing RNA–RNA, RNA‐protein and protein–protein interactions shape the compaction and function of RNPs throughout their lifetime and may provide novel therapeutic targets in ...

Kidney Mass Reduction Leads to l‐Arginine Metabolism‐Dependent Blood Pressure Increase in Mice

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundUninephrectomy (UNX) is performed for various reasons, including kidney cancer or donation. Kidneys being the main site of l‐arginine production in the body, we tested whether UNX mediated kidney mass reduction impacts l‐arginine metabolism and

The Pharmacodynamics of L-Arginine [PDF]

open access: yesThe Journal of Nutrition, 2007
L-arginine is a precursor for nitric oxide (NO) synthesis. NO is a ubiquitous mediator that is formed by a family of enzymes named NO synthases. In the brain, NO acts as a neurotransmitter; in the immune system, NO acts as a mediator of host defense; and in the cardiovascular system, NO mediates the protective effects of the intact endothelium, acting ...
