Time-resolved fluorescence study of conformational dynamics in opioid peptides

Article Abstract:

Research was conducted to examine the temperature-dependent rotational behavior of opiod pentapeptides, DPDPE, DPDPE and (Leu5)-enkephalin using a time-resolved analogue of the steady-state temperature dependence. Fluorescence decays were calculated by time-correlated single-photon counting. Results indicate that the thermal viscosity effect can be related to the loss of internal motion of the peptide as temperature decreases.
