Reports from Commissions

Commission on Biophysical Chemistry (I.7)

Summary of Minutes of Commission Meeting at IUPAC General Assembly, Berlin, Germany, 8-9 August 1999

"Recommendations for the presentation of NMR structures of proteins and nucleic acids" by J. L. Markley, A. Bax, Y. Arata, C. W. Hilbers, R. Kaptein, B. D. Sykes, P. E. Wright, and K. Wüthrich has been published in Pure and Applied Chemistry (Vol. 70, No. 1, pp. 117-142, 1998). To broaden its scientific impact, it has also been published in the Journal of Biomolecular NMR, the European Journal of Biochemistry, and Biochemistry. This important report will help to define how NMR results on macromolecules will be reported in the literature. Hans-J�rgen Hinz and Fred Schwarz reported on the status of their project "Recommendations for the measurement and the analysis of results obtained on biological substances with differential scanning calorimetry (DSC)." Their report contains a discussion of the basis of DSC as applied to biochemical denaturations, how one should use these instruments, and how the results should be analyzed and presented in the literature. This document is close to its final form. A major addition to the previous version is the inclusion of experimental results for lysozyme unfolding which were obtained from several participating laboratories. In a joint meeting with the Electroanalytical Chemistry Commission (V.5), Daniel Thévenot reported on his project "Electrochemical biosensors: Recommended definitions and classification." This project, which is concerned primarily with terminology pertinent to electrochemical biosensors, is also close to completion now that the issue of 'single-use" and "multiple-use" biosensors appears to have been resolved.

Two additional projects may be completed in the near future: "Redox potential measurements of proteins", which was reported on by George Wilson, and "Terminology in the field of lipid vesicles (liposomes)", which was reported on by Helmut Hauser. The latter project would have been completed except for the untimely death of Dimitri Papohadjopoulos, a key member of the working party. Two future projects that the Commission sees value in include "Recommendations for the measurement and analysis of results obtained by isothermal titration calorimetry (ITC)" and "Guidelines for the presentation of the results from computational chemistry."

Productive, joint meetings were also held with Commission I.2 (Thermodynamics), Commission I.3 (Electrochemistry), Commission I.6 (Colloid, Surface Chemistry, and Catalysis), and Commission V.5 (Electroanalytical Chemistry). Kurt Wüthrich will succeed Helmut Hauser on 1 January 2000 as the Chairman of the Commission on Biophysical Chemistry (I.7).
