Cyclic nucleotides are second messengers that are essential in vision, muscle contraction, neurotransmission, exocytosis, cell growth, and, differentiation. These molecules are degraded by a family of enzymes known, as phosphodiesterases, which serve a critical function by regulating the, intracellular concentration of cyclic nucleotides. We have determined the, three-dimensional structure of the catalytic domain of phosphodiesterase, 4B2B to 1.77 angstrom resolution. The active site has been identified and, contains a cluster of two metal atoms. The structure suggests the, mechanism of action and basis for specificity and will provide a framework, for structure-assisted drug design for members of the phosphodiesterase, family.

CATALYTIC DOMAIN OF HUMAN PHOSPHODIESTERASE 4B2B

Overview

Cyclic nucleotides are second messengers that are essential in vision, muscle contraction, neurotransmission, exocytosis, cell growth, and differentiation. These molecules are degraded by a family of enzymes known as phosphodiesterases, which serve a critical function by regulating the intracellular concentration of cyclic nucleotides. We have determined the three-dimensional structure of the catalytic domain of phosphodiesterase 4B2B to 1.77 angstrom resolution. The active site has been identified and contains a cluster of two metal atoms. The structure suggests the mechanism of action and basis for specificity and will provide a framework for structure-assisted drug design for members of the phosphodiesterase family.

About this Structure

1F0J is a Single protein structure of sequence from Homo sapiens with , and as ligands. Active as 3',5'-cyclic-nucleotide phosphodiesterase, with EC number 3.1.4.17 Full crystallographic information is available from OCA.
