Paper Abstract

Earlier a comprehensive study of reaction substrate, product and their complexes with the enzyme has been carried out by means of stationary fluorescence spectroscopy. A hypothesis has been suggested according to which protein changes its conformation during the reaction. In this respect it is quite interesting to study both static and dynamic properties of the enzyme molecule. Luckily, according to genetic engineering data, luciferase molecule contains only one tryptophan residue, which makes it a very convenient object for the studies by means of time-resolved fluorescence spectroscopy. The scope of this paper is the study of luciferase tryptophan fluorescence. The methods applied were fluorescence spectrochronography and anisotropy decay analysis.
