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:
“What exacerbates the strain in the working class is the absence of money to pay for services they need, economic insecurity, poor daycare, and lack of dignity and boredom in each partner’s job. What exacerbates it in upper-middle class is the instability of paid help and the enormous demands of the career system in which both partners become willing believers. But the tug between traditional and egalitarian models of marriage runs from top to bottom of the class ladder.”
—Arlie Hochschild (20th century)
