Oxygen equilibrium properties of myoglobin locked in the liganded and unliganded conformations.

A comparison of the O(2) equilibrium curves of sperm-whale myoglobin locked in the liganded (CO-bound) and unliganded (deoxy) conformations by encapsulation in a wet porous sol-gel silica reveals a marked difference between them. The CO-bound state-locked myoglobin showed a nearly monophasic (hyperbolic) O(2) equilibrium curve with a dissociation constant… CONTINUE READING
