  • Solubilization of Membrane-bound Rod Phosphodiesterase by the Rod Phosphodiesterase Recombinant δ Subunit
    Journal of Biological Chemistry, 1996
    Co-Authors: Stephanie K. Florio, Rabi K. Prusti, Joseph A Beavo
    Abstract:

    Abstract Retinal rod and cone Phosphodiesterases are oligomeric enzymes that consist of a dimeric catalytic core (α′2 in cones and αβ in rods) with inhibitory subunits (γ) that regulate their activity. In addition, a 17-kDa protein referred to as the δ subunit co-purifies with the rod soluble Phosphodiesterase and the cone Phosphodiesterase. We report here partial protein sequencing of the rod δ subunit and isolation of a cDNA clone encoding it. The predicted amino acid sequence is unrelated to any other known protein. Of eight bovine tissue mRNA preparations examined by Northern analysis, the strongest δ subunit-specific signal was present in the retina. A less intense signal was seen in the brain and adrenal mRNA. In bovine retinal sections, rod δ subunit anti-peptide antibodies label rod but not cone outer segments. δ subunit, added back to washed outer segment membranes, solubilizes a large fraction of the membrane-bound Phosphodiesterase, indicating that this subunit binds to the classical membrane associated Phosphodiesterase. The subunit forms a tight complex with native, but not trypsin-released Phosphodiesterase, suggesting that the isoprenylated carboxyl termini of the catalytic subunits may be involved in binding of the δ subunit to the Phosphodiesterase holoenzyme.

  • The role of protein phosphorylation in the regulation of cyclic nucleotide Phosphodiesterases.
    Molecular and Cellular Biochemistry, 1993
    Co-Authors: J Beltman, W K Sonnenburg, Joseph A Beavo
    Abstract:

    The cyclic nucleotide Phosphodiesterases constitute a complex superfamily of enzymes responsible for catalyzing the hydrolysis of cyclic nucleotides. Regulation of cyclic nucleotide Phosphodiesterases is one of the two major mechanisms by which intracellular cyclic nucleotide levels are controlled. In many cases the fluctuations in cyclic nucleotide levels in response to hormones is due to the hormone responsiveness of the Phosphodiesterase. Isozymes of the cGMP-nhibited, cAMP-specific, calmodulin-stimulated and cGMP-binding Phosphodiesterases have been demonstrated to be substrates for protein kinases. Here we review the evidence that hormonally responsive phosphorylation acts to regulate cyclic nucleotide Phosphodiesterases. In particular, the cGMP-inhibited Phosphodiesterases, which can be phosphorylated by at least two different protein kinases, are activated as a result of phosphorylation. In contrast, phosphorylation of the calmodulin-stimulated Phosphodiesterases, which coincides with a decreased sensitivity to activation by calmodulin, results in decreased Phosphodiesterase activity.

  • primary sequence of cyclic nucleotide Phosphodiesterase isozymes and the design of selective inhibitors
    Trends in Pharmacological Sciences, 1990
    Co-Authors: Joseph A Beavo, David H Reifsnyder
    Abstract:

    Primary sequence information has been reported for more than 15 different mammalian cyclic nucleotide Phosphodiesterases. Moreover, recent observations suggest that many of these isozymes are selectively expressed in a limited number of cell types. The fact that nearly all these different Phosphodiesterases have unique primary sequences in their catalytic or regulatory domains and that they are often selectively expressed implies that it may be possible to modulate individual isozymes using specific drugs. Joe Beavo and David Reifsnyder summarize much of the evidence that has led to our current understanding of multiple isozymes of Phosphodiesterase, with emphasis on aspects that may be relevant to drug design. They also discuss why many previous attempts to isolate isozyme-selective inhibitors may have failed.

  • cyclic nucleotide Phosphodiesterases functional implications of multiple isoforms
    Physical Review, 1995
    Co-Authors: Joe Beavo
    Abstract:

    In the last few years there has been a veritable explosion of knowledge about cyclic nucleotide Phosphodiesterases. In particular, the accumulating data showing that there are a large number of different Phosphodiesterase isozymes have triggered an equally large increase in interest about these enzymes. At least seven different gene families of cyclic nucleotide Phosphodiesterase are currently known to exist in mammalian tissues. Most families contain several distinct genes, and many of these genes are expressed in different tissues as functionally unique alternative splice variants. This article reviews many of the more important aspects about the structure, cellular localization, and regulation of each family of Phosphodiesterases. Particular emphasis is placed on new information obtained in the last few years about how differential expression and regulation of individual Phosphodiesterase isozymes relate to their function(s) in the body. A substantial discussion of the currently accepted nomenclature is also included. Finally, a brief discussion is included about how the differences among distinct Phosphodiesterase isozymes are beginning to be used as the basis for developing therapeutic agents.

  • structure and mechanism of a bacterial light regulated cyclic nucleotide Phosphodiesterase
    Nature, 2009
    Co-Authors: Thomas R. M. Barends, Elisabeth Hartmann, Mark Gomelsky, Dmitri A. Ryjenkov, Julia J. Griese, Thorsten Beitlich, Natalia V. Kirienko, Jochen Reinstein, Robert L. Shoeman, Ilme Schlichting
    Abstract:

    BLUF is a photoreceptor protein domain that uses an FAD chromophore to sense blue light. Although X-ray crystal structures of single-domain BLUF proteins have been determined, there have not been any reports of a structure of a BLUF protein that also contained a functional 'output' domain. For this reason, the mechanism(s) of light activation for this class of photoreceptors has remained enigmatic. Here, Thomas Barends and colleagues report the first biochemical, structural, and mechanistic characterization of a full-length, active photoreceptor. The protein is from the bacterium Klebsiella pneumoniae, and it contains the BLUF sensor domain and a Phosphodiesterase output domain that hydrolyses cyclic dimeric GMP. The structures of this protein co-complexed with its substrate and metal ions provide a detailed understanding of how light absorbed by the BLUF domain leads to activation of the Phosphodiesterase output domain. Although structures of single-domain BLUF proteins—a photoreceptor protein domain that senses blue light—have been determined, there have been no reports of the structure of a BLUF protein containing a functional output domain; for this reason, the mechanism of light activation has remained enigmatic. The first biochemical, structural and mechanistic characterization of a full-length, active photoreceptor containing a BLUF sensor domain and a Phosphodiesterase EAL output domain is now reported. The ability to respond to light is crucial for most organisms. BLUF is a recently identified photoreceptor protein domain that senses blue light using a FAD chromophore1. BLUF domains are present in various proteins from the Bacteria, Euglenozoa and Fungi. Although structures of single-domain BLUF proteins have been determined2,3,4, none are available for a BLUF protein containing a functional output domain; the mechanism of light activation in this new class of photoreceptors has thus remained poorly understood. Here we report the biochemical, structural and mechanistic characterization of a full-length, active photoreceptor, BlrP1 (also known as KPN_01598), from Klebsiella pneumoniae5. BlrP1 consists of a BLUF sensor domain and a Phosphodiesterase EAL output domain which hydrolyses cyclic dimeric GMP (c-di-GMP). This ubiquitous second messenger controls motility, biofilm formation, virulence and antibiotic resistance in the Bacteria6,7,8,9. Crystal structures of BlrP1 complexed with its substrate and metal ions involved in catalysis or in enzyme inhibition provide a detailed understanding of the mechanism of the EAL-domain c-di-GMP Phosphodiesterases. These structures also sketch out a path of light activation of the Phosphodiesterase output activity. Photon absorption by the BLUF domain of one subunit of the antiparallel BlrP1 homodimer activates the EAL domain of the second subunit through allosteric communication transmitted through conserved domain–domain interfaces.
