121. Comparison of Backbone Dynamics of Oxidized and Reduced Putidaredoxin by ^u15^N NMR Relaxation Measurements
Topic: Chemical Analysis
Published: 8/3/1999
Authors: Fahriye Nese Sari, Marcia J Holden, M P. Mayhew, V L. Vilker, B Coxon
Abstract: The backbone dynamics of uniformly ^u15^N-labeled reduced and oxidized putidaredoxin (Pdx) have been studied by 2D ^u15^N NMR relaxation measurements. ^u15^N T^d1^ and T^d2^ values and ^u1^H-^u15^N NOE s have been measured for the diamagnetic region ...

122. Kinetic Characterization of Chiral Biocatalysis of Cycloarenes by the Camphor 5-Monooxygenase Enzyme System
Topic: Chemical Analysis
Published: 6/15/1999
Authors: D A Grayson, V L. Vilker
Abstract: Redox enzyme mediated biocatalysis has the potential to regio - and stereo-specificity oxidive hydrocarbons producing valuable products with minimal by-product formation. In-vitro reactions of the Camphor (cytochrome P-450) 5-monooxygenase enzyme sy ...

123. Evaluation of Analytical Methodologies for Non-Intrusive Drug Testing--Supercritical Fluid Extraction of Cocaine from Hair
Topic: Chemical Analysis
Published: 3/1/1999
Authors: J F Morrison, L T Sniegoski, W J Yoo, Alim A Fatah
Abstract: Supercritical fluid extraction (SFE) was investigated as an environmentally friendly alternative to currently used wet chemical procedures in hair drug testing protocols. The SFE behavior of cocaine and its primary metabolite benzoylecgonine was stud ...

126. Vibrationally-Resolved Sum-Frequency Generation With Broad Bandwidth Infrared Pulses
Topic: Chemical Analysis
Published: 10/15/1998
Authors: Lee J Richter, T Petralli-Mallow, John C. Stephenson
Abstract: We present a novel procedure for vibrationally-resolved sum-frequency generation (SFG) in which a broad-bandwidth IR pulse is mixed with a narrow-bandwidth visible pulse. The resultant SFG spectrum is dispersed with a spectrograph and detected in pa ...

Topic: Chemical Analysis
Published: 9/9/1998
Authors: A. E. Roitberg, Marcia J Holden, M P. Mayhew, I V Kurnikov, D N Beratan, V L. Vilker
Abstract: A necessary step in understanding biological function in multiple metalloprotein redox systems is the description of protein-protein binding and electron transfer between two distant metal centers. In this communication, we present experimental and ...
