[Tryptophan fluorescence of Na+,K+-ATPase preparations]. / Issledovanie triptofanovoi fluorestsentsii preparatov Na+, K+-ATFazy

ABSTRACT

On the strength of the study of tryptophan fluorescence of Na+, K+-ATPase preparation a conclusion about conformational changes of the enzume molecule at the level of its tertiary structure is made. The largest changes of intensity and position of fluorescence spectrum consequently the macromolecule structure are discovered at the formation of Mg-ATP-enzyme complex.
