Initial structure activity relationships (SAR) demonstrated that structural changes distal to the THIQ moiety were well-tolerated and able to show improvements in potency and absorption, distribution, metabolism, and excretion (ADME) properties. Compounds 1 and 2 (Fig. 7) were both active in the ...
The complex structure of c-JMJD5 and a symmetric dimethyl arginine (DM(s)-Arg). (A) Complex structure of DM(s)-Arg and c-JMJD5. (B) Omit map 2Fo-Fc electron density of DM(s)-Arg with contour level 1σ. (C) The coordination of elements at catalytic center. (D) The binding po...
The sequential polypeptides (L-Arg-X-Gly)n, where X represents amino acid residues Ala, Val, and Leu, were prepared as models of arginine-rich histones to be used in studying their structure and their interactions with DNA. The polymerization was carried out on the pentachlorophenyl active ...
The arginine residue consists of a guanidino group on its side chain, which is protonated and positively charged at physiological pH3,5. The guanidino group forms multiple hydrogen bonds that bind with other interacting proteins or cofactors2,5. Although the methylated arginine residue retains its p...
The fluorescence microscopy results of the LIVE/DEAD intracellular viability marker for the upper (Figure 7C, keratinocytes) and lower (Figure 7D, fibroblasts) faces of the same 3D structure are presented in Figure 7. For each side of the construct, live cells (green fluorescence, LIVE column)...
(black boxes). The less conserved β-barrel structure (grey boxes) folds against the catalytic region to form the protein substrate binding cleft[77]. Additional specific motifs, such as the SH3 domain (SH3), the zinc finger (ZnF), the myristoylation motif (Myr), the FBox motif and the...
Through its RNA chaperone function, AUF1 p45 can destabilize the stem structure at the 3′end of the viral RNA to accelerate structural rearrangement and viral RNA cyclization. Importantly, PRMT1-mediated arginine methylation within the C-terminal RGG motif (R272/278/280/282/345) enhances AUF1 ...

A 7-mer of arginine eluted from a heparin-affinity column at 0.82 M NaCl, whereas the analogous 7-mer of lysine eluted at 0.64 M . Similarly, the putative heparin binding site peptide (amino acid residues 110–130) from acidic fibroblast growth factor, which contained four lysine and two ...
MG-H1 was built on to structural models of HDL at R27, R123 and R149 and changes of bonding interactions identified. The N-terminal domain containing R27 was not part of the proposed trefoil structural model;36 rather the structure assumed was that based on the crystal structure of an N-...
