In this study novel glycosylated MAAs were found in the terrestrial cyanobacterium Nostoc commune (N. commune). An MAA with an absorption maximum at 334 nm was identified as a hexose-bound porphyra-334 derivative with a molecular mass of 508 Da. Another MAA with an absorption maximum at 322 nm was identified as a two hexose-bound palythine-threonine derivative with a molecular mass of 612 Da. These purified MAAs have radical scavenging activities in vitro, which suggests multifunctional roles as sunscreens and antioxidants. The 612-Da MAA accounted for approximately 60% of the total MAAs and contributed approximately 20% of the total radical scavenging activities in a water extract, indicating that it is the major water-soluble UV-protectant and radical scavenger component. The hexose-bound porphyra-334 derivative and the glycosylated palythine-threonine derivatives were found in a specific genotype of N. commune, suggesting that glycosylated MAA patterns could be a chemotaxonomic marker for the characterization of the morphologically indistinguishable N. commune. The glycosylation of porphyra-334 and palythine-threonine in N. commune suggests a unique adaptation for terrestrial environments that are drastically fluctuating in comparison to stable aquatic environments. © 2013 by the authors.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00010309","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Ocean University of China, MDPI"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/md11093124","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA1203626X","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1660-3397","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nazifi, Ehsan"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wada, Naoki"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Yamaba, Minami"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Asano, Tomoya"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Nishiuchi, Takumi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Matsugo, Seiichi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Sakamoto, Toshio"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-SAKAMOTO-T-03124.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-SAKAMOTO-T-03124.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10322/files/SC-PR-SAKAMOTO-T-03124.pdf"},"version_id":"132c8cff-52ee-47b7-a69d-838b18809883"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Glycosylated porphyra-334 and palythine-threonine from the terrestrial cyanobacterium nostoc commune","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Glycosylated porphyra-334 and palythine-threonine from the terrestrial cyanobacterium nostoc commune"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10322","relation_version_is_last":true,"title":["Glycosylated porphyra-334 and palythine-threonine from the terrestrial cyanobacterium nostoc commune"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T08:47:24.600254+00:00"}
