PROTEINS IN ELECTRIC-FIELDS AND PRESSURE FIELDS - EXPERIMENTAL RESULTS

Experimental results obtained by Stark effect and pressure tuning opti cal spectroscopy are discussed with the emphasis on studies aimed at u nraveling the coupling of prosthetic groups to proteins. A comparative , detailed analysis is given concerning the coupling of the heme group to the apoprotein in various heme proteins based on spectral hole bur ning data. Electrochromism and electric dichroism experiments related to the coupling problem are also discussed in the context of other pro tein systems. (C) 1998 Elsevier Science B.V. All rights reserved.
