Published: December 2006

The effects of hypocrellin A (HA) on the conformational changes of hemoglobin and myoglobin were studied using synchronous fluorescence spectroscopy. The results indicated that HA can change the conformation of these two proteins, leading to the change in the micro-environment of tryptophane and tyrosine residues from hydrophobic environment to hydrophilic environment to different extent.
