The met and deoxy forms of sperm whale myoglobin (Mb) can be unfolded by guanidine hydrochloride (GuHCl). Electronic absorption and circular dichroism spectroscopic measurements show that folded deoxyMb is more stable than the folded met protein. Laser excitation of NADH generates species that rapid...
