Determination of the intramolecular tyrosine-tryptophan distance in a 7-peptide related to the C-terminal sequence of cholecystokinin.

Abstract

The solution conformation of a 7-peptide with the C-terminal sequence of cholecystokinin was investigated by evaluation of intramolecular resonance energy transfer between tyrosine (donor) in position 1 and tryptophan (acceptor) in position 4. From the relative enhancement of acceptor fluorescence a transfer efficiency of 0.70 +/- 0.04 was determined. The… (More)
