Mutations in Cancer Cause Gain of Cysteine, Histidine, and Tryptophan at the Expense of a Net Loss of Arginine on the Proteome Level

open access: yesBiomolecules, 2017
Accumulation of somatic mutations is critical for the transition of a normal cell to become cancerous. Mutations cause amino acid substitutions that change properties of proteins.

L-arginine supplementation minimizes aging-induced changes in the sperm chromatin of roosters

open access: yesPoultry Science, 2023
: Arginine is the main amino acid that constitutes the sperm protamine of roosters, named galline, which complexes with sperm DNA, allowing high compaction of its chromatin. Arginine supplementation has positive effects on semen quality in aged roosters,

The influence of L-arginine on the self-medication behaviour of Drosophila Melanogaster larvae

open access: yes, 2013
The theory of self-medication works on the premise that sick animals will change their diet to incorporate food substances that are not part of their usual diet, that will cure or alleviate the disease.

Arginine-dependent mRNA destabilization.

open access: yes, 2019
(A) A partial diagram of polyamine biosynthesis. Putrescine can be produced from ornithine via speC and speF encoding a constitutive and inducible ornithine decarboxylase, respectively or from arginine in two steps via speA and speB encoding arginine ...

Arginine Kinase Activates Arginine for Phosphorylation by Pyramidalization and Polarization

open access: yesACS Catalysis
Arginine phosphorylation plays numerous roles throughout biology. Arginine kinase (AK) catalyzes the delivery of an anionic phosphoryl group (PO3-) from ATP to a planar, trigonal nitrogen in a guanidinium cation. Density functional theory (DFT) calculations have yielded a model of the transition state (TS) for the AK-catalyzed reaction.

l-NG-nitro arginine (l-NOARG), a novel, l-arginine-reversible inhibitor of endothelium-dependent vasodilatation in vitro

open access: yes, 1990
1 The effect of l-NG-nitro arginine (l-NOARG) was compared with that of l-NG-monomethyl arginine (l-NMMA) on vasodilatation of the isolated aorta of the rabbit and perfused mesentery of the rat in response to acetylcholine (ACh) and sodium nitroprusside

Effects of L-Arginine Supplementation during Late Gestation on Reproductive Performance, Piglet Uniformity, Blood Profiles, and Milk Composition in High Prolific Sows

open access: yesAnimals, 2020
This study was conducted to evaluate the effects of L-arginine supplementation levels during late gestation on reproductive performance and piglet uniformity in high prolific sows. A total of 60 F1 multiparous sows (Yorkshire × Landrace), with an average
