Guanidine group of arginine
Guanidine group of arginine-Besides being the most alkaline amino acid, the arginine molecule contains a positively charged guanidine group, similar to guanidine hydrochloride, and has been used in many refolding systems to suppress protein aggregation Our results showed that arginine caused the inactivation and unfolding of aminoacylase, with no aggregation during denaturation A comparison between theGuanidine Group The side chain of arginine is a considerably stronger base than from BCM 3024 at University of South Florida

H group is mobile and can be transferred to the arginine guanidine group For M 2Cu H ions, deprotonation of the SH/SO 3 H group is energetically more favorable than that of the carboxyl group, and the resulting thiolate/sulfonate group plays an important role in the coordination structure of M 2Cu H ions, as well as the fragmentationThe guanidinium functional group is commonly used by proteins and enzymes to recognize and bind anions using ion pairing and hydrogen bonding The specific patterns of hydrogen bonding and the great basicity of the guanidine functional group allowWith 12 sidechain atoms and a molecular weight of about 174 Da, arginine is one of the largest standard amino acids From a geometric viewpoint, arginine is very interesting because of the guanidinium group –NH–C– (NH 2) 2 in its side chain (Fig 1) At physiological pH, guanidinium is always protonated and positively charged
Glycosylation of arginine is unique because the guanidine group of arginine has a high acid dissociation constant value and representing an extremely poor nucleophile Recently, the crystal structures of NleB, SseKs, EarP, arginine GlcNAcylated death domaincontaining proteins, NleB/FADDDD, and EarP/EFP/dTDPβLrhamnose were solved by our group and otherLa guanidine est un composé cristallin formé lors de l'oxydation de la guanineElle est utilisée dans la production de plastiques et d'explosifs Elle se trouve également dans l'urine, étant un produit du métabolisme Elle n'est pas commercialisée telle quelle, mais sous forme de sel (chlorhydrate, acétate, carbonate, etc)Elle peut également céder un protonA comparison between the unfolding of aminoacylase in aqueous and HCl (pH 75) arginine solutions indicated that the guanidine group of arginine had
The arginine molecule is a zwitterion with the guanidyl group, rather than the primary α amino group, accepting extra proton from carboxylic acid group (Ref1) Protonated or not, when consider guanidine as a molecule, there shouldn't be any s p 3 nitrogen in the molecule because it is resonancestabilized moleculeIndeed, arginine–arginine pairing has been frequently found in structural protein databases In particular, when strengthened by a presence of negatively charged glutamate, aspartate, or Cterminal carboxylic groups, this binding motif helps to stabilize peptide or protein dimers and is also found in or near active sites of several enzymesThe likecharge pairing of the guanidinium sideAlso, the chemical shift ( ppm) of carbon in the guanidine group is close to the chemical shift of carbon in the guanidine group in larginine ( ppm) Thus, the detailed analysis of the onedimensional and twodimensional NMR spectra on 1 H and 13 C nuclei make it possible to confirm the structure of Lys2Arg dendrimer Moreover, the ratio of CH, CH 2 –(N) and CH 2

· Once the importance of larginine was established, research was focused on the relation between the guanidinium group and the penetrating ability Remarkably, guanidiniumrich synthetic molecules such as oligopeptoids 33 and oligocarbamates 38 ( Fig 4 ) demonstrated comparable or even higher translocation ability with respect to l arginine nonamer (R9) · This arginine preference may result from the unique hydration properties of the side chain guanidinium group which facilitates its movement through aSymmetric dimethylarginine (sDMA, omegaNG,N'Gdimethylarginine), where one methyl group is placed on each of the two terminal guanidine nitrogens of arginine;
