Copper in Nonvertebrate Organisms
Probably all living cells in organisms of almost all phyla contain the fundamental enzyme of respiration, cytochrome c oxidase. On this basis alone, copper is probably essential for all living creatures. Cytochrome oxidase has been discussed in detail in Chapter 6, including the one- to three-subunit forms found in bacteria and the somewhat larger forms found in plants and other creatures. It will not be discussed again in any detail in this chapter. However, the other important copper enzymes and redox proteins and the distribution and functions of copper in nonvertebrate organisms will be described and summarized herein.
