Class II AC
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:
“There is ... a class of fancies, of exquisite delicacy, which are not thoughts, and to which, as yet, I have found it absolutely impossible to adapt language.... Now, so entire is my faith in the power of words, that at times, I have believed it possible to embody even the evanescence of fancies such as I have attempted to describe.”
—Edgar Allan Poe (1809–1849)
