Cancelled Professor Audrey Lamb from the University of Texas at San Antonio will present a seminar. Evidence for the chemical mechanism of dihydroxybutanone phosphate (DHBP) synthase from riboflavin biosynthesis Abstract: RibB (3,4-dihydroxy-2-butanone 4-phosphate synthase) is a magnesium-dependent enzyme that excises the C4 of D-ribulose-5-phosphate (D-Ru5P) as formate. This chemistry forms the four-carbon substrate for RibE (lumazine synthase) that is incorporated into the xylene moiety of lumazine and ultimately the riboflavin isoalloxazine. The reaction was first identified in studies by Bacher [...]

Professor Loi Do from the University of Houston will present a seminar. Catalytic Agents to Detoxify Reactive Aldehyde Species Abstract Although the human body has natural defenses against reactive aldehydes species (e.g., α,β-unsaturated aldehydes, α-ketoaldehydes, dialdehydes, etc.), these systems are often impaired in patients with pathological conditions such as neurodegenerative disorders, cardiovascular diseases, or cancer. Reactive aldehydes species can disrupt living systems by alkylating nucleic acids, crosslinking proteins, and consuming essential antioxidants. Although there are currently no FDA-approved treatments for [...]

Professor Dom Qualley from Berry College will present a seminar. Gag (dis)order: structure and dynamics of a retroviral polyprotein Host: Dr. Stephen Woski

Professor Josh Figueroa from the University of California, San Diego will present a seminar. The Carbonyl-Isocyanide Relationship and Beyond   Abstract: Recent results concerning the synthesis and reactivity of low-coordinate transition-metal complexes featuring sterically encumbering m-terphenyl isocyanide ligands are presented. Given the isolobal relationship between organoisocyanides and carbon monoxide, these complexes serve as mimics of the unsaturated binary metal carbonyls. The latter have traditionally been studied in either the gas phase or by matrix-isolation techniques and, consequently, their condensed-phase reactivity [...]
