“Analysis & Ramifications of D-Amino Acids and Peptide Epimers in Biological Systems”
Investigations on the occurrence and biochemical roles of free D-amino acids, as well as D-amino acids containing peptides and proteins in living systems have increased in frequency and significance. (1-3) We now understand some of the biosynthetic and regulatory pathways involved in the occurrence and roles of D-amino acids and peptides epimers in human neurologic diseases and cancer. Peptide epimers have the same exact mass as their all L-AA counterparts making identification and analysis difficult. (4) Also the fact that they are rare and are in complex biological matrices further complicates the situation. In the realm of post-transitional modifications (PTMs) of peptide/protein, epimerization is rarely considered. We show that this can play a profound role in further PTMs and in subsequent peptide/protein function. Effects on kinase and glycosylase function are illustrated and discussed.

About the Program Speaker
Daniel W. Armstrong is the Welch Distinguished Professor of Chemistry and Biochemistry at the University of Texas at Arlington. He has > 800 publications and received over 35 awards for teaching and research, including numerous ACS Awards, the Chirality Medal and the Pittsburgh Analytical Chemistry Award. He has been named one of the top 10 analytical scientists in the world by Analytical Scientist magazine and was elected to the National Academy of Inventers in 2014. He has mentored and graduated over 120 Ph.D. analytical chemists. Dr. Armstrong developed the most comprehensive solvation and characterization models for room temperature ionic liquids (RTILs) and pioneered their use in analytical chemistry. He also developed ILs as the most versatile MS reagents. His work was significantly responsible for the chromatography–led revolution in chiral separations. He has developed the field of D-Amino Acids in biological systems. He has developed rapid, high efficiency, microfluidic methods for analyzing microorganisms.
