Summary The optical spectrum of the primary peroxide compound of myeloperoxidase (compound I) is reported. The spectrum, obtained in 1 msec after mixing native ferric myeloperoxidase with excess hydrogen peroxide, exhibits a Soret maximum at 425 nm (c = 52 mM −1 cm −1 ) and an increase in extinction of the ferric peroxidase at wavelengths higher than 607 nm. The spectrum suggests a structure for compound I of myeloperoxidase similar to those of horseradish peroxidase and catalase. Compound I… CONTINUE READING
