CRYSTAL STRUCTURE OF A DIELS-ALDERASE CATALYTIC ANTIBODY 1E9 IN COMPLEX WITH ITS HAPTEN

Overview

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.

About this Structure

1C1E is a Protein complex structure of sequences from Mus musculus with ENH and DMR as ligands. The following page contains interesting information on the relation of 1C1E with [Antibodies]. Full crystallographic information is available from OCA.
