Abstract
The cytochromes of the filamentous bacteriaStreptomyces clavuligerus andSaccharopolyspora erythraea have been studied by low-temperature (77K) difference spectra and room-temperature potentiometric titrations. Difference spectra of membranes fromSa. erythraea indicate the presence of twoc- and twob-type cytochromes. A furtherb-type cytochrome is revealed by potentiometric titration. The soluble and membrane-bound forms of a green pigment, believed to be involved in electron transport to oxygen, are each shown to have complex absorption spectra which, in the case of the soluble form, may be potentiometrically resolved into several components. Threeb-type and threec-type cytochromes are shown to be present in the membranes ofSt. clavuligerus.
