Abstract: From the temperature dependence of fluorescence quenching kinetics, a novel temperaturesensitive structure transition was discovered in a donor-acceptor labeled peptides. Perfect agreement of related abrupt changes in a1,t1 andt2 gives strong support for the existence of this structure transition, which suggests it is possible to develop peptides that can be rapidly and reversibly switched between two structure states in response to temperature shift.
