(A) MCD and (B) UV-Vis spectra of oxyferrous H93G Mb in the presence of CPSH (5 mM) (dashed line; MCD data enlarged 1.66-fold) and THT (5 mM) (solid line). The spectra were recorded in a 60/40 (v/v) mixture of ethylene glycol/0.1 M potassium phosphate buffer (pH 7.0) at -40 °C. Reproduced from reference [26] with permission of the copyright holders.
