Presence of cytochromed in respiratory particles ofStreptomyces griseus and its function in the terminal oxidation system

The cytochromed inStreptomyces griseus was studied by means of difference spectra measured under dithionite- or substrate-reduction. Results indicated that the pigment 625 ofStreptomyces griseus is ad-type cytochrome. Its pyridine hemochrome showed the difference maximum at 613 nm. The difference maximum of the reduced cytochromed was shifted to the red by… (More)
