Respiratory Electron Transport Systems of Aquatic Fungi. I. Leptomitus lacteus and Apodachlya punctata
Abstract
The electron transport systems of 2 species of aquatic fungi, Leptomitus lacteus and A podachlya punctata, contained cytochrome a-a(3) (605 mmu), 2 b type cytochromes (564 and 557 mmu), c type cytochrome (551 mmu), and flavoprotein, but they appeared to lack cytochrome c(1). Reduced-minus-oxidized difference spectra and difference spectra in the presence of antimycin A or cyanide were used to characterize these systems. Studies with the electron microscope revealed that hyphae of Leptomitus lacteus contained numerous, conspicuous mitochondria with tubular cristae.
