Professors Rachel Powers and Paul Cook and four of their students attended the national meeting of the American Crystallographic Association in New Orleans (May 26-30, 2017). Powers lab member Rachel Springsdorf (BMS) presented a poster on her research that explores boronic acids as inhibitors of class D beta-lactamases. Dr. Powers co-chaired a session with Dr. Joe Tanski (Vassar College) entitled “Engaging undergraduate students with crystallographic research”. Also presenting posters were Cook lab members Aaron Rosenberg and Emily David (Crystallographic and fluorescence-based ligand binding analysis of BshC: the putative cysteine ligase in bacillithiol biosynthesis) and Chris Royer (Structural and Functional Analysis of the Bacillithiol Biosynthesis Enzyme BshA Supports the SNi-like Retaining Mechanism).
