$^{19}F$-NMR studies to understand pH induced structural changes in protective antigen anthrax toxin
(Wichita State University, 2022-04-29)Anthrax bacteria ($Bacillus$ $anthracis$) produces Protective antigen toxin (PA), Lethal factor (LF) and Edema factor (EF) protein components into the host cells. Protective antigen toxin (PA83 - 83kDa polypeptide) binds ... -
Design, synthesis and biological evaluation of small molecules with potential antibacterial and antiviral activity
(Wichita State University, 2022-05)In recent years, the ongoing explosion of antibiotic-resistance and viral infections has posed a major threat to global public health and called for the development of new therapeutics. Here, a set of novel compounds are ... -
A$_2$P$_2$S$_6$ (A = Ba and Pb): a good platform to study the polymorph effect and lone pair effect to form an acentric structure
(The Royal Society of Chemistry, 2022-05-14)Three ternary thiophosphates α-Ba$_2$P$_2$S$_6$, β-Ba$_2$P$_2$S$_6$, and Pb$_2$P$_2$_S$_6$ were synthesized via a high temperature salt flux method or an I2 transport reaction. β-Ba$_2$P$_2$S$_6$ and Pb$_2$P$_2$S$_6$ were ... -
Structure of the anthrax protective antigen D425A dominant negative mutant reveals a stalled intermediate state of pore maturation
(Elsevier, 2022-05-15)The tripartite protein complex produced by anthrax bacteria (Bacillus anthracis) is a member of the AB family of β-barrel pore-forming toxins. The protective antigen (PA) component forms an oligomeric prepore that assembles ... -
Evolution of structure and transport properties of the Ba$_8$Cu$_{16}$P$_{30}$ clathrate-I framework with the introduction of Ga
(American Institute of Physics Inc., 2022-05-09)Two type-I clathrates were synthesized by introducing Ga into the framework of the Ba$_8$Cu$_{16}$P$_{30}$ type-I clathrate. The introduction of minute amounts of Ga, 1.9% Ga/Mtotal (where $M_{total}$ = Cu + Ga), resulted ... -
Assessing the Dipole Moments and Directional Cross Sections of Proteins and Complexes by Differential Ion Mobility Spectrometry
(American Chemical Society, 2022-05-02)Ion mobility spectrometry (IMS) has become a mainstream approach to fractionate complex mixtures, separate isomers, and assign the molecular geometries. All modalities were grouped into linear IMS (based on the absolute ... -
