Advanced X-ray absorption spectroscopy : Analyzing electronic structures of catalysts

DOI: OA:W3021031383 Authors: Jean‐Pierre H. Oudsen Abstract: In catalysis, it is important to know the exact structure of the catalyst, especially under catalytic conditions. Spectroscopic information on the catalyst is crucial to reveal for example structure-activity...

The Kinetic Reaction Mechanism of the Vibrio cholerae Sodium-dependent NADH Dehydrogenase

DOI: 10.1074/jbc.m115.658773 Authors: Karina Tuz, Katherine G. Mezic, Tianhao Xu, Blanca Barquera, Oscar Juárez Abstract: The sodium-dependent NADH dehydrogenase (Na(+)-NQR) is the main ion transporter in Vibrio cholerae. Its activity is linked to the operation of the...

On-grid and in-flow mixing for time-resolved cryo-EM

DOI: 10.1107/s2059798321008810 Authors: David P. Klebl, Howard D. White, Frank Sobott, Stephen P. Muench Abstract: Time-resolved cryo-electron microscopy (TrEM) allows the study of proteins under non-equilibrium conditions on the millisecond timescale, permitting the...

The Mechanisms of Catalysis by Metallo β‐Lactamases

DOI: 10.1155/2008/576297 Authors: Michael I. Page, Adriana Badarau Abstract: Class B beta-lactamases or metallo-beta-lactamases (MBLs) require zinc ions to catalyse the hydrolysis of beta-lactam antibiotics such as penicillins, cephalosporins, carbapenems, and...
