CSB Core Update
Feb. 21, 2024—The Biophysical Instrumentation Core and the Megalab Core have been combined to form the new Vanderbilt Center for Structural Biology Labs and Instrumentation Facility. The facility supports mass photometry, biolayer interferometry, stopped-flow spectrometry, microscale thermophoresis, dynamic light scattering, circular dichroism and microcalorimetry instruments for measuring macromolecular conformation, stability and binding interactions. The facility also provides...
Enzyme substrate positioning dynamics: To be electrostatic or not to be?
Feb. 9, 2024—Bioengineered enzymes are used in a wide variety of applications including chemical synthesis, waste degradation, fuel production, disease diagnosis and treatment. The development of efficient enzymes can be accelerated by understanding the catalytic origin of enzymes, a fundamental question in the field of chemistry. Catalysis is believed to rely largely on protein dynamics, one facet...
Ben Brown receives grant to develop nonaddictive painkillers with AI
Feb. 2, 2024—Ben Brown, assistant research professor in chemistry, was recently awarded $2.375M to develop nonaddictive painkillers with AI. The grant, an Avenir Award in Chemistry and Pharmacology of Substance Use Disorders, is awarded by NIDA to early-stage investigators who propose highly innovative studies and represent the future of addiction science. Ben’s research will focus on Mu-opioid...
John Yang appointed to JCTC Early Career Board
Feb. 2, 2024—John Yang, assistant professor of chemistry, was recently appointed to the inaugural Early Career Board (ECB) for the Journal of Chemical Theory and Computation (JCTC). The ECB initiative provides young investigators with guidance and insight into the editorial process as they pursue their independent research careers. The members will also provide input on journal strategies, act...
Eli McDonald presents Karpay Award Seminar January 23
Jan. 19, 2024—2024 Karpay Award Winner Eli McDonald, of the Meiler and Plate Labs, gives the MBTP/CSB Seminar on Tuesday, January 23, at 12:20pm in 1220 MRB3. Eli was drawn to scientific research from an early age. He studied the molecular dynamics of phospholipid bilayer self-assembly as an undergraduate at Vanderbilt University before joining Jens Meiler and...
Delving into polymerase α-primase dynamics
Jan. 5, 2024—In eukaryotes, DNA replication relies on the synthesis of a chimeric RNA/DNA primer by the heterotetrameric polymerase α-primase (pol-prim) enzyme. The primers generated by pol-prim consist of 7-10 ribonucleotides followed by ~20 deoxyribonucleotides and are generated by distinct active sites in the primase and polymerase subunits. Both primase and polymerase α consist of a catalytic...
A new toxin toolkit for C. diff
Dec. 1, 2023—Clostridioides difficile (C. diff) is a leading cause of diarrhea and healthcare-associated infections in the United States and recognized as an urgent threat by the Centers for Disease Control. Virulence of C. diff infections is believed to rely primarily on the production of two toxins: TcdA and TcdB. TcdA and TcdB are large homologous proteins...
Eli McDonald wins Karpay Award
Nov. 10, 2023—Congratulations to Eli McDonald, of the Meiler and Plate Labs, for being named the 2024 recipient of The Karpay Award in Structural Biology. “I am truly honored by this recognition,” Eli said. Eli has worked in the Meiler and Plate labs for four and a half years studying Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) using...
Is DZA the new DNA? Structural and functional studies of a novel artificial pairing system
Nov. 3, 2023—Xeno nucleic acids (XNAs) are artificial pairing systems that replace the traditional deoxyribonucleic acid (DNA) system present in most organisms. XNAs are of particular interest in the discovery and development of therapeutics as synthetic molecules offer a wider range of metabolic stability, uptake, distribution and binding partners compared to native oligonucleotides. One of the most...
