In order to elucidate the mechanism of isoaspartate formation within the Asp45-Glu46 sequence of Ustilago sphaerogena ribonuclease U2 based on three-dimensional structure, crystal structures of ribonuclease U2 complexed with adenosine 3\u0027-monophosphate have been solved at 0.96 and 0.99 \u00c5 resolution. The crystal structures revealed that the C atom of Asp45 is located just beside the main-chain N atom of Glu46 and that the conformation which is suitable for succinimide formation is stabilized by a hydrogen-bond network mediated by water molecules 190, 219 and 220. These water molecules are suggested to promote the formation of isoaspartate via succinimide: in the succinimide-formation reaction water 219 receives a proton from the N atom of Glu46 as a general base and waters 190 and 220 stabilize the tetrahedral intermediate, and in the succinimide-hydrolysis reaction water 219 provides a proton for the N atom of Glu46 as a general acid. The purine-base recognition scheme of ribonuclease U2 is also discussed.", "subitem_description_type": "Abstract"}]}, "item_2_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "1712", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u91ce\u53e3, \u4fee\u6cbb"}]}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "International Union of Crystallography"}]}, "item_2_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1107/S0907444910019621", "subitem_relation_type_select": "DOI"}}]}, "item_2_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright International Union of Crystallography"}]}, "item_2_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10885500", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09074449", "subitem_source_identifier_type": "ISSN"}]}, "item_2_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "499", "subitem_subject_scheme": "NDC"}]}, "item_2_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Journal Article"}]}, "item_2_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Graduate School of Pharmaceutical Sciences, The University of Tokyo"}, {"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u5927\u5b66\u9662\u85ac\u5b66\u7cfb\u7814\u7a76\u79d1 \u86cb\u767d\u69cb\u9020\u751f\u7269\u5b66\u6559\u5ba4"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Noguchi, Shuji"}], "nameIdentifiers": [{"nameIdentifier": "1711", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-05-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "snoguhi_u2-3AMP_ActaD.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1400000.0, "url": {"label": "snoguhi_u2-3AMP_ActaD.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/500/files/snoguhi_u2-3AMP_ActaD.pdf"}, "version_id": "dae717ac-8274-48ed-b62c-bc3e061389d1"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "aspartate isomerization", "subitem_subject_scheme": "Other"}, {"subitem_subject": "isoaspartate", "subitem_subject_scheme": "Other"}, {"subitem_subject": "succinimide", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Isomerization mechanism of aspartate to isoaspartate implied by structures of Ustilago sphaerogena ribonuclease U2 complexed with adenosine 3\u0027-monophosphate", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Isomerization mechanism of aspartate to isoaspartate implied by structures of Ustilago sphaerogena ribonuclease U2 complexed with adenosine 3\u0027-monophosphate"}]}, "item_type_id": "2", "owner": "1", "path": ["9/10/11", "20/119/120"], "permalink_uri": "http://hdl.handle.net/2261/37930", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2010-11-02"}, "publish_date": "2010-11-02", "publish_status": "0", "recid": "500", "relation": {}, "relation_version_is_last": true, "title": ["Isomerization mechanism of aspartate to isoaspartate implied by structures of Ustilago sphaerogena ribonuclease U2 complexed with adenosine 3\u0027-monophosphate"], "weko_shared_id": null}
