201. Spectroscopy of 2-aminopurine: An MCSCF Study
Topic: Life Sciences Research
Published: 12/1/1998
Authors: E L Rachofsky, J B Ross, Morris Krauss, R Osman
Abstract: 2-aminopurine (2AP) is a highly fluorescent isomer of adenine that can be incorporated into DNA as a probe of structure, dynamics, and protein-DNA interactions. Interpretation of the fluorescence of 2AP in DNA requires a model of the electronic stru ...

204. Binding and Electron Transfer Between Putidaredoxin and Cytochrome P450cam (CYP101). Theory and Experiments
Topic: Life Sciences Research
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 ...

205. Exploration of the Structural Environment of the Iron-Sulfur Cluster in Putidaredoxin by Nitrogen-15 NMR Spectroscopy of Selectively Labeled Cysteine Residues
Topic: Life Sciences Research
Published: 8/28/1998
Authors: Fahriye Nese Sari, Marcia J Holden, M P. Mayhew, V L. Vilker, B Coxon
Abstract: Putidaredoxin is a di-iron protein whose paramagnetic region is not well characterized by ^u1^H detected NMR. We have studied the structure of this region in greater detail by directly observed ^u15^N NMR of oxidized and reduced putidaredoxin prepar ...

206. Conformational Changes in the Crystal Structure of Rat Glutathione Transferase M1-1 with Global Substitution of 3-Fluorotyrosine for Tyrosine
Topic: Life Sciences Research
Published: 8/14/1998
Authors: G Xiao, J F Parsons, K Tesh, R N Armstrong, G L. Gilliland
Abstract: The structure of the tetradeca-(3-fluorotyrosyl) M1-1 GSH transferase (3-Ftyr GSH transferase), a protein in which tyrosine residues are globally substituted by 3-fluorotyrosines, has been determined at 2.2 resolution. This variant was produced t ...
