744–747. 1965.—Photochemical data showed that the only oxidase found in the cyanide-sensitive cells of
Achromobacter
was cytochrome
o
, and that cyanide-resistant cells contained at least two oxidases. The oxidase responsible for cyanide resistance was a pigment the CO compound of which had its absorption band at a wavelength longer than 580 mμ. In addition, kinetic data suggested that there were two oxidases having different affinities for cyanide. From the data presented, resistance to cyanide in
Achromobacter
strain D was attributed to the induced formation of cytochrome
a
2
, which has a very low affinity for cyanide. Several characteristics of cytochrome
a
2
as a cytochrome oxidase are summarized.
