Following the end of the first decade in catalytic antibody research, recent efforts are reflecting a more introspective view of the field. Notably, X-ray crystal structure analyses of antibody catalysts are permitting an increased understanding of the evolution and modus operandi of these remarkable biocatalysts. Additionally, the breadth and scope of new antibody-catalyzed reactions and novel hapten design strategies have continued to flourish with support from an increasing number of contributors to this ever expanding area.
