Binding specificity of hydrolytic catalytic antibody: lessons from the diverse immune system.
The diverse immune system has the potential to provide numerous antibodies that catalyze a great variety of reactions and exhibit diversity in mechanism and substrate specificity. However, to find such an antibody is not practical, unless we understand the immune response precisely and utilize it. We applied an alternative screening methodology based on the binding specificity of antibodies for the structure of the transition-state analog p-nitrophenyl phosphonate in order to study the built-in diversity of the immune response. This study uncovered the unpredictable binding and substrate specificity of catalytic antibodies derived from the diverse immune response.
