3'-cyclic nucleotide 3'-phosphodiesterase
1. A spectrophotometric assay of 2':3'-cyclic nucleotide 3'-phosphodiesterase (EC 3.1.4.37) based on the use of an acid-base indicator and a buffer having identical PKa values is described. The assay is sinmple and rapid; it was particularly convenient for monitoring the enzyme activity at vat :ous stages of purification. 2. Several proteinases were examined for their ability to solubilize 2':3...
متن کامل2',3'-Cyclic nucleotide 3'-phosphodiesterase is associated with mitochondria in diverse adrenal cell types.
In this study, we have examined the expression and intracellular localisation of the myelin protein 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP) in bovine adrenal medullary chromaffin cell cultures. By immunoblotting, using two distinct anti-CNP monoclonal antibodies, CNP was detected in medullary cell cultures and expression of CNP was confirmed by reverse transcription and PCR amplifica...
متن کاملAn Unusual Phage Repressor Encoded by Mycobacteriophage BPs
Temperate bacteriophages express transcription repressors that maintain lysogeny by down-regulating lytic promoters and confer superinfection immunity. Repressor regulation is critical to the outcome of infection-lysogenic or lytic growth-as well as prophage induction into lytic replication. Mycobacteriophage BPs and its relatives use an unusual integration-dependent immunity system in which th...
متن کاملCyclic nucleotide phosphodiesterase 3 signaling complexes.
The superfamily of cyclic nucleotide phosphodiesterases is comprised of 11 gene families. By hydrolyzing cAMP and cGMP, PDEs are major determinants in the regulation of intracellular concentrations of cyclic nucleotides and cyclic nucleotide-dependent signaling pathways. Two PDE3 subfamilies, PDE3A and PDE3B, have been described. PDE3A and PDE3B hydrolyze cAMP and cGMP with high affinity in a m...
متن کاملMyomegalin is a novel protein of the golgi/centrosome that interacts with a cyclic nucleotide phosphodiesterase.
Subcellular targeting of the components of the cAMP-dependent pathway is thought to be essential for intracellular signaling. Here we have identified a novel protein, named myomegalin, that interacts with the cyclic nucleotide phosphodiesterase PDE4D, thereby targeting it to particulate structures. Myomegalin is a large 2,324-amino acid protein mostly composed of alpha-helical and coiled-coil s...
