Enzymes are cleaving the substrate. If the substrate is DNA they are called restriction enzymes. Activating enzymes will cut off the domain that is biological active to become functional.
Immunoglobulin E (IgE) kappa or Fc specific antibody is a kind of antibody (or immunoglobulin (Ig) "isotype") that has only been found in mammals. IgE is synthesized by plasma cells. Monomers of IgE consist of two heavy chains (ε chain) and two light chains, with the ε chain containing 4 Ig-like constant domains (Cε1-Cε4). IgEs play a role in allergy and response to parasite infection. High levels of IgEs caused by parasites can lower the allergic reaction of patients to allergens common present in the human environment. As such the parasite history of an allergic patient needs to be taken in consideration as a positive factor.
