Is Arginine Charged in a Membrane? [PDF]
Biophysical Journal, 2008 "Charged" amino acids play countless important roles in protein structure and function. Yet when these side chains come into contact with membranes we do not fully understand their behavior. This is highlighted by a recent model of voltage-gated ion channel activity and translocon-based experiments that suggest small penalties to expose these side ...

To Be or Not To Be a Molecular Ion: The Role of the Solvent in Photoionization of Arginine. [PDF]
, 2019 Application of photoionization mass spectroscopy, a technique capable of assessing protonation states in complex molecules in the gas phase, is challenging for arginine due to its fragility. We report photoionization efficiencies in the valence region of

ADP-ribosylation of arginine [PDF]
Amino Acids, 2010 Arginine adenosine-5'-diphosphoribosylation (ADP-ribosylation) is an enzyme-catalyzed, potentially reversible posttranslational modification, in which the ADP-ribose moiety is transferred from NAD(+) to the guanidino moiety of arginine. At 540 Da, ADP-ribose has the size of approximately five amino acid residues.

Non-Histone Arginine Methylation by Protein Arginine Methyltransferases [PDF]
Current Protein & Peptide Science, 2020 Protein arginine methyltransferase (PRMT) enzymes play a crucial role in RNA splicing, DNA damage repair, cell signaling, and differentiation. Arginine methylation is a prominent posttransitional modification of histones and various non-histone proteins that can either activate or repress gene expression.

Regulation of arginine transport by GCN2 eIF2 kinase is important for replication of the intracellular parasite Toxoplasma gondii [PDF]
, 2019 Toxoplasma gondii is a prevalent protozoan parasite that can infect any nucleated cell but cannot replicate outside of its host cell. Toxoplasma is auxotrophic for several nutrients including arginine, tryptophan, and purines, which it must acquire from ...

Entropic stabilization of proteins and its proteomic consequences [PDF]
, 2005 We report here a new entropic mechanism of protein thermostability due to residual dynamics of rotamer isomerization in native state. All-atom simulations show that Lysines have much greater number of accessible rotamers than Arginines in folded states of proteins.

Electron Attachment to DNA: The Protective Role of Amino Acids [PDF]
, 2022 We have studied the effect of amino acids on electron attachment properties of DNA nucleobases, taking cytosine as a model system. The equation of motion coupled cluster theory with an extended basis set has been used to simulate the electron-attached state of the DNA model system. Four selected amino acids, Arginine, Alanine, Lysine, and Glycine which

Histone arginine methylation [PDF]
FEBS Letters, 2010 Arginine methylation is a common posttranslational modification (PTM). This type of PTM occurs on both nuclear and cytoplasmic proteins, and is particularly abundant on shuttling proteins. In this review, we will focus on one aspect of this PTM: the diverse roles that arginine methylation of the core histone tails play in regulating chromatin function.
