Hi All,<br><div class="gmail_quote"><br>I am performing molecular docking and molecular dynamics simulations of the thiazolidinedione pioglitazone binding to the PPAR-gamma receptor protein (PDB ID: 1ZGY). The thiazolidinedione ring can exist in numerous different tautomeric states; I have attached a figure depicting several of them. Which tautomer would be dominant at the physiological pH of ~7.0?<br>
<br>Also, are there any software programs that can predict which tautomer would be correct?<br><br>Thanks in advance,<br>Nancy<br></div>
