title: Properties of Ascaris muscle mitochondria. 1. Cytochromes.
abstract: 1. The cytochrome system in Ascaris muscle mitochondria was further characterized using purer preparations. 2. Difference spectra (at 22 degrees C and -196 degrees C) of the mitochondrial preparations using succinate and ascorbate plus N,N,N' ,N'-tetramethyl-p-phenylenediamine show that Ascaris muscle mitochondria contain cytochromes c1, c and aa3, and also at least three b-type cytochromes. The b-type cytochrome is the predominant component. 3. Cytochrome c and Ascaris cytochrome b-560 can be extracted from the mitochondrial preparations with 150mM KCl, leaving the membrane-bound cytochromes c1, b and aa3 in the KCl residue.
