Peptide Conformational Dynamics and Vibrational Stark Effects Following Photoinitiated Disulfide Cleavage

Peptide Conformational Dynamics and Vibrational Stark Effects Following Photoinitiated Disulfide Cleavage

Photoinitiation of relaxation of two peptides (labeled 1 and 2) and spectroscopic studies of the ensuing dynamics have led to new information about peptide conformational dynamics. Following photolysis of the aryl disulfide chromophore that constrains a peptide to be distorted from its equilibrium f...

Zusammenfassung:Photoinitiation of relaxation of two peptides (labeled 1 and 2) and spectroscopic studies of the ensuing dynamics have led to new information about peptide conformational dynamics. Following photolysis of the aryl disulfide chromophore that constrains a peptide to be distorted from its equilibrium form, the S−S bond is broken in
