    Global efforts in structural genomics (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-10-06
    Description: A worldwide initiative in structural genomics aims to capitalize on the recent successes of the genome projects. Substantial new investments in structural genomics in the past 2 years indicate the high level of support for these international efforts. Already, enormous progress has been made on high-throughput methodologies and technologies that will speed up macromolecular structure determinations. Recent international meetings have resulted in the formation of an International Structural Genomics Organization to formulate policy and foster cooperation between the public and private efforts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, R C -- Yokoyama, S -- Wilson, I A -- P50 GM62411/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Oct 5;294(5540):89-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Center for Structural Genomics, Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11588249" target="_blank"〉PubMed〈/a〉

    Crystal structure of the anti-viral APOBEC3G catalytic domain and functional implications (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-10-14
    Description: The APOBEC family members are involved in diverse biological functions. APOBEC3G restricts the replication of human immunodeficiency virus (HIV), hepatitis B virus and retroelements by cytidine deamination on single-stranded DNA or by RNA binding. Here we report the high-resolution crystal structure of the carboxy-terminal deaminase domain of APOBEC3G (APOBEC3G-CD2) purified from Escherichia coli. The APOBEC3G-CD2 structure has a five-stranded beta-sheet core that is common to all known deaminase structures and closely resembles the structure of another APOBEC protein, APOBEC2 (ref. 5). A comparison of APOBEC3G-CD2 with other deaminase structures shows a structural conservation of the active-site loops that are directly involved in substrate binding. In the X-ray structure, these APOBEC3G active-site loops form a continuous 'substrate groove' around the active centre. The orientation of this putative substrate groove differs markedly (by 90 degrees) from the groove predicted by the NMR structure. We have introduced mutations around the groove, and have identified residues involved in substrate specificity, single-stranded DNA binding and deaminase activity. These results provide a basis for understanding the underlying mechanisms of substrate specificity for the APOBEC family.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2714533/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2714533/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holden, Lauren G -- Prochnow, Courtney -- Chang, Y Paul -- Bransteitter, Ronda -- Chelico, Linda -- Sen, Udayaditya -- Stevens, Raymond C -- Goodman, Myron F -- Chen, Xiaojiang S -- R01 AI055926/AI/NIAID NIH HHS/ -- R01 AI055926-05/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Nov 6;456(7218):121-4. doi: 10.1038/nature07357.

    Biased signaling pathways in beta2-adrenergic receptor characterized by 19F-NMR (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-24
    Description: Extracellular ligand binding to G protein-coupled receptors (GPCRs) modulates G protein and beta-arrestin signaling by changing the conformational states of the cytoplasmic region of the receptor. Using site-specific (19)F-NMR (fluorine-19 nuclear magnetic resonance) labels in the beta(2)-adrenergic receptor (beta(2)AR) in complexes with various ligands, we observed that the cytoplasmic ends of helices VI and VII adopt two major conformational states. Changes in the NMR signals reveal that agonist binding primarily shifts the equilibrium toward the G protein-specific active state of helix VI. In contrast, beta-arrestin-biased ligands predominantly impact the conformational states of helix VII. The selective effects of different ligands on the conformational equilibria involving helices VI and VII provide insights into the long-range structural plasticity of beta(2)AR in partial and biased agonist signaling.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3292700/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3292700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Jeffrey J -- Horst, Reto -- Katritch, Vsevolod -- Stevens, Raymond C -- Wuthrich, Kurt -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073197-08/GM/NIGMS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- U54 GM094618-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 2;335(6072):1106-10. doi: 10.1126/science.1215802.
