Title:
Evolution of shape complementarity and catalytic efficiency from a primordial antibody template.

Science. 1999 Dec 17;286(5448):2345-8.
Abstract:
The crystal structure of an efficient Diels-Alder antibody catalyst at 1.9 angstrom resolution reveals almost perfect shape complementarity with its transition state analog. Comparison with highly related progesterone and Diels-Alderase antibodies that arose from the same primordial germ line template shows the relatively subtle mutational steps that were able to evolve both structural complementarity and catalytic efficiency.
