One possibility is that the E3-defective Peli1 may exert an active role by binding to, and modulate the function of, other Peli family members.
The water molecule conserved in the structure plays an important role in binding to the long branch, whereas Asp496 and the main chain of Phe497 form hydrogen bonds with fragment hits in the short branch.
We present a hybrid computational methodology to predict multiple energetically accessible conformations for G protein-coupled receptors (GPCRs) that might play a role in binding to ligands and different signaling partners.
The invariance of these residues for all the sequences available during the 1970s thus could plausibly be attributed to their crucial role in binding to the heme via their distinctive side chains.
A discrete region of the HA's tip that plays a critical role in binding to cells, they found, has a 95% similarity in amino acid sequence between the old and new pandemic strains.
Our results indicate that Abi1 might play an additional role in binding to active Rac1 in the complex (Fig. 8A).
To test its role in binding to CB3, dot-blot experiments with wild type M-protein and a set of variants with mutations in PARF [5] were conducted.
It is possible that limited flexibility of this unique Ubc9 structure may play a role in binding to the Uba2 ufd.
Key residues in the RBD [13] predicted to have a role in binding to human receptors (T98Y, S136T, 153W, 183H) were found to be Y98, S136, W153 and H183 in the Indian isolates as in other H1N1pdm viruses.
Among these, acetylcholine plays a prominent role by binding to the muscarinic cholinergic receptors which activate the PLC-InsP3 pathway to elevate cytosolic calcium and facilitate insulin vesicle exocytosis [36].
Arg17 of the ligand contributed to the free energy difference of Gly935 considerably by attractive van der Waals and electrostatic interactions; hence emphasizing the role on binding to the receptor.
