3.1.4.53 | catalytic domain of inactive mutant D201N in complex with substrate cAMP at 1.56 A resolution. Q369 forms only one hydrogen bond ith the adenine of cAMP. Structural comparison between isoform PDE4D2-cAMP and PDE10A2-cAMP shows an anti configuration of cAMP in PDE4, but syn in PDE10 |
3.1.4.53 | hanging drop method, PDE4D2 in complex with the nonselective inhibitor 3-isobutyl-1-methylxanthine |
3.1.4.53 | hanging-drop vapor-diffusion method, crystal structures of the catalytic domain of phosphodiesterase 4B complexed with AMP (2.0 A), 8-Br-AMP (2.13 A), and rolipram (2.0 A) |
3.1.4.53 | in complex with inhibitor 4-[8-(3-nitrophenyl)-[1,7]naphthyridin-6-yl]benzoic acid, comparison with isoforms PDE4A, PDE4B, PDE4C. Inhibitor binds in the same conformation to the deep cAMP substrate pocket and interacts with the same residues in each instance. Detailed structural comparison |
3.1.4.53 | in complex with inhibitor 4-[8-(3-nitrophenyl)-[1,7]naphthyridin-6-yl]benzoic acid, comparison with isoforms PDE4A, PDE4C, PDE4D. Inhibitor binds in the same conformation to the deep cAMP substrate pocket and interacts with the same resiudues in each instance. Detailed structural comparison |
3.1.4.53 | in complex with inhibitor 4-[8-(3-nitrophenyl)-[1,7]naphthyridin-6-yl]benzoic acid, comparison with isoforms PDE4B, PDE4C, PDE4D. Inhibitor binds in the same conformation to the deep cAMP substrate pocket and interacts with the same residues in each instance. Detailed structural comparison |
3.1.4.53 | molecular dynamics simulations. The second bridging ligand in the active site is HO- rather than H2O, serving as a nucleophile to initialize the catalytic hydrolysis of cAMP |
3.1.4.53 | NMR and CD analysis of the N-terminal 38mer peptide of isoform PDE4D5 which contains the entire signaling scaffold protein RACK1 interaction domain together with a portion of the beta-arrestin binding site. The peptiode has a distinct amphipathic helical structure. Study on binding to RACK1 and to beta-arrestin |
3.1.4.53 | unliganded PDE8A1 and in complex with 3-isobuytl-1-methylxanthine, hanging drop vapour diffusion method, using 100 mM sodium cacodylate (pH 6.5), 15% 2-propanol, 30% ethylene glycol, and 8-10% PEG3350 at 4°C |
3.1.4.53 | unliganded, detailed structural comparison with isoforms PDE4A, PDE4B, PDE4C |
