title: [Cytochromes of the luminescent bacterium, Photobacterium fischeri, their solubilization and relationship to luminescence].
abstract: The hemoprotein composition of the luminescent bacterium Photobacterium fischeri was studied, in particular, the distribution of cytochromes among the bacterial fractions, viz. cell-free extract, supernatant, "particles", protein preparation. The hemochromogenic analysis has shown that the principal hemoproteins of Photobacterium fischeri are cytochromes, with hemes of the b and c type. The activity of luciferase is distributed with hemoproteins. The purified preparation of luciferase contains cytochrome of the b type that has been identified as mixed functions oxidase--P-450.
