Adenylate cyclase magnesium ions

The documentation, by example, of ail of the major Mg-requiring enzymes of the body would lead to a very long discussion. Magnesium is required at various steps in the synthesis of DNA, RNA, and protein. The metal ion is required by various enzyn es participating in the synthesis of carbohydrates and lipids. Mg ions play a structural role, where they are bound to phospholipid membranes, ribosomes, and chromatin. Mg Lons are required by enzymes that are used in transmitting signals w ithin cells. These enzymes include adenylate cyclase, w hich... 

The complexity of the membranes and of the adenyl cyclase assay medium have forced postponement of further evaluation of the role of magnesiums and other ions.
