Crystallized mammalian carboxylesterase polypeptide and screening methods employing same

摘要

Solved three-dimensional crystal structures of mammalian carboxylesterases (CEs) are disclosed. A solved three-dimensional crystal structure of a rabbit CE polypeptide co-crystallized with 4PP is disclosed. Solved three-dimensional structures of a human CE polypeptide co-crystallized with tacrine and a human CE polypeptide co-crystallized with homatropine are disclosed. The disclosed structures can be employed in the design of CE modulators. Methods of designing modulators of the biological activity of rabbit CE, human CE and other CE polypeptides, are also disclosed.
