ABSTRACT
|
|
|
| |
|
Phosphodiesterases (PDEs) modulate signaling by cyclic nucleotides in diverse
processes such as cardiac contractility, platelet aggregation, lipolysis,
glycogenolysis, and smooth muscle contraction. Cyclic guanosine monophosphate
(cGMP) stimulated human phosphodiesterase 2 (PDE2) is expressed mainly in brain
and heart tissues. PDE2A is involved in the regulation of blood pressure and
fluid homeostasis by the atrial natriuretic peptide (ANP), making PDE2-type
enzymes important targets for drug discovery. The design of more potent and
selective inhibitors of PDE2A for the treatment of heart disease would be
greatly aided by the identification of active site residues in PDE2A that
determine substrate and inhibitor selectivity. The identification of active site
residues through traditional mutational studies involves the time-consuming and
tedious purification of a large number of mutant proteins from overexpressing
cells. Here we report an alternative approach to rapidly produce active site
mutants of human PDE2A and identify their enzymatic properties using a wheat
germ in vitro translation (IVT, also known as cell-free translation) system. We
also present the crystal structure of the catalytic domain of human PDE2A
determined at 1.7 A resolution, which provided a framework for the rational
design of active site mutants. Using a rapid IVT approach for expression of
human PDE2A mutants, we identified the roles of active site residues Asp811,
Gln812, Ile826, and Tyr827 in inhibitor and substrate selectivity for PDE2A.

only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
