These AC's are toxins secreted by pathogenic bacteria such as Bacillus anthracis and Bordetella pertussis during infection. These bacteria also secrete proteins that enable the AC-II to enter host cells, where the exogenous AC activity undermines normal cellular processes. The genes for Class II AC's are known as cyaA. Several crystal structures are known for AC-II enzymes.

Famous quotes containing the word class:
“We believe that Carlyle has, after all, more readers, and is better known to-day for this very originality of style, and that posterity will have reason to thank him for emancipating the language, in some measure, from the fetters which a merely conservative, aimless, and pedantic literary class had imposed upon it, and setting an example of greater freedom and naturalness.”
—Henry David Thoreau (1817–1862)
