Disulfide bonds are formed by pairs of this amino acid which also contains a sulfhydryl side chain. To test for side chain interactions implicit in this model we inspected interactions of the side chains of arginine and lysine with each of the 19 non glycine amino acids in proteins in the protein data bank.

The cover illustrates a new nmr method to characterise functional interactions formed by arginine sidechains.
Arginine side chain interactions. A free sidechain fast exchange and one engaged in a saltbridge slow exchange are shown. In addition water is often found to be involved in ligand binding to proteins mediating ligand interactions with polar or charged side chain or main chain atoms. It can cause some side effects such as abdominal pain bloating diarrhea gout blood abnormalities allergies airway inflammation worsening of asthma and low blood pressure.
Although not all of these side effects may occur if they do occur they may need medical attention. Read the full text of the article at 101002cphc201800598. Igor vorobyov ilsoo kim zhen t.
Arginine side chain interactions and the role of arginine as a gating charge carrier in voltage sensitive ion channels. Arginine residues are often crucial to many biological interaction interfaces because the flexible arginine sidechain consisting of a chain of aliphatic carbon atoms and a terminal guanidinium group is capable of an array of hydrogenbonds and other interactions. It is useful to remember that the energy of a hydrogen bond depending on the distance between the donor and the acceptor and the angle between them is in the range of 2 10 kcalmol.
Amino acid with pka near neutral ph an imidazole side chain and it must be supplied by the diet. Some of the dosage forms listed on this page may not apply to the brand name l arginine. L arginine is possibly safe for most people when taken appropriately by mouth administered as a shot or applied to the skin short term.
The methodology presented provides an important step towards characterising interactions of arginine sidechains in enzymes in phase separation and in protein interaction interfaces in general. Scientific reports 2016 6 1 doi. Along with its needed effects arginine the active ingredient contained in l arginine may cause some unwanted effects.
