Arginine, Arg

It is a peptide containing 27 amino acid residues containing the amino acids L-histidine (His) L-aspartic acid (Asp) L-serine (Ser) glycine (Gly) L-threonine (Thr) L-phenyl-alanine (Phe) L-glutamic acid (Glu) L-glutamine [Glu(NHj)] L-leucine (Leu) L-arginine (Arg) L-alanine (Ala) and L-valinamide (Va -NHj). 

The C-terminal extension (residues 163-179) of the Rieske proteins of the bef complex appears to have the same role in stabilizing the open side of the cluster binding subdomain as the helix-loop insertion in the mitochondrial Rieske protein. The C-terminal part of RFS contains a fully conserved arginine (Arg 170 in spinach) this arginine... 

Recent work has identified a critical role for a conserved arginine Arg-34 in the N-terminus for agonist binding and receptor activation, loss of which leads to a dysfunctional receptor [134].

The antibodies can also act like entropy traps by stabilizing a particular conformation of a substrate that is favorable to the formation of the TS. It is the case of the antibody 1F7 catalyzing the transformation of chorismate into prephenate," which stabilizes, thanks to several hydrogen bonds and an ionic bond between an arginine (Arg H95) and a carboxylate substituent of the substrate, the conformation of the chorismate which will give rise to the TS in a chair conformation for this reaction (Figure 11).
