Examining the Mechanics of Chiral Recognition in Phosphotriesterase and Molecular Micelles
MetadataShow full item record
Chiral recognition plays an important role in the many places including chiral chromatography and the biological world where many enzymes are enantioselective. Understanding how molecular micelles and enzymes like phosphotriesterase are able to detect and distinguish isomers can help explain how chiral drugs or compounds are consumed within the body. The binding of 1,1'-binaphthyl-2,2'-diyl hydrogen phosphate to a molecular micelle containing a dipeptide head group was explored using NMR spectroscopy. Similarly, enzyme kinetics were used to study how site-target mutagenesis affected the enzymatic site of phosphotriesterase. In both cases, it was found that a macromolecules ability to detect chirality changed when the residues within the binding pocket of each changed.
