pubpic2010xxWe explore the use of carbon-deuterium (C-D) bonds under time-resolved conditions to follow the unfolding of cytochrome c from a photostationary state that accumulates after CO is photodissociated from the protein’s heme prosthetic group. Our results clearly show that C-D bonds are well-suited to characterize protein folding and dynamics.
