Exploring Structure-Activity Relationships In Molecular Catalysts For C-H Bond Oxidation And Co2 Reduction, Zane Turner Jan 2023

Exploring Structure-Activity Relationships In Molecular Catalysts For C-H Bond Oxidation And Co2 Reduction, Zane Turner

Electronic Theses and Dissertations

Value-added chemicals can be generated by the functionalization of hydrocarbon substrates by C-H bond oxidation and by the reduction of carbon dioxide (CO2), where each of these processes require long-lived catalysts that are selective and efficient. Chemical feedstocks such as petroleum-derived hydrocarbons and carbon dioxide are inexpensive and readily accessible but are challenging to transform into more valuable compounds. The oxidative functionalization of unactivated C-H bonds is a difficult task because they are, in general, thermodynamically stable and kinetically inert. Bioinspired iron-oxo catalysts have shown great promise in this area, but often have limited activity, selectivity, and/or stability. In this …

Discovery Of A Lectin Domain That Regulates Enzyme Activity In Mouse N-Acetylglucosaminyltransferase-Iva (Mgat4a), Masamichi Nagae, Tetsuya Hirata, Hiroaki Tateno, Sushil K. Mishra

Faculty and Student Publications

N-Glycosylation is a common post-translational modification, and the number of GlcNAc branches in N-glycans impacts glycoprotein functions. N-Acetylglucosaminyltransferase-IVa (GnT-IVa, also designated as MGAT4A) forms a β1-4 GlcNAc branch on the α1-3 mannose arm in N-glycans. Downregulation or loss of GnT-IVa causes diabetic phenotypes by dysregulating glucose transporter-2 in pancreatic β-cells. Despite the physiological importance of GnT-IVa, its structure and catalytic mechanism are poorly understood. Here, we identify the lectin domain in mouse GnT-IVa’s C-terminal region. The crystal structure of the lectin domain shows structural similarity to a bacterial GlcNAc-binding lectin. Comprehensive glycan binding assay using 157 glycans and solution NMR …

A Distinct Mechanism Of C-Type Inactivation In The Kv-Like Kcsa Mutant E71v, Ahmed Rohaim, Bram J. A. Vermeulen, Jing Li, Felix Kümmerer

Faculty and Student Publications

C-type inactivation is of great physiological importance in voltage-activated K+ channels (Kv), but its structural basis remains unresolved. Knowledge about C-type inactivation has been largely deduced from the bacterial K+ channel KcsA, whose selectivity filter constricts under inactivating conditions. However, the filter is highly sensitive to its molecular environment, which is different in Kv channels than in KcsA. In particular, a glutamic acid residue at position 71 along the pore helix in KcsA is substituted by a valine conserved in most Kv channels, suggesting that this side chain is a molecular determinant of function. Here, a combination of X-ray crystallography, …
