It catalyzes the transfer of the <jats:italic>p</jats:italic>‐coumaric acid and caffeic acid from their CoA esters to the 5‐glucosyl moiety of anthocyanidin 3,5‐diglucosides but could not use malonyl‐CoA as an acyl donor. Neither anthocyanidin 3‐monoglucoside nor anthocyanins aromatically acylated at the 3‐glucosyl moiety could be acylated by this enzyme. Aromatic acylation of anthocyanidin 3,5‐diglucoside by this enzyme caused a bathochromic shift and increased pigment stability in neutral to weakly basic pH. Other anthocyanins from the petals of <jats:italic>G. triflora</jats:italic> were isolated and their structures were determined by fast‐atom‐bombardment MS and NMR. The biosynthetic pathway of genti‐odelphin, a diacylated anthocyanin accumulating in <jats:italic>G. triflora</jats:italic> petals, is proposed on the basis of these results.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388844222856577","@type":"Researcher","foaf:name":[{"@value":"Hiroyuki Fujiwara"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844222856578","@type":"Researcher","foaf:name":[{"@value":"Yoshikazu Tanaka"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844222856576","@type":"Researcher","foaf:name":[{"@value":"Yuko Fukui"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844222856581","@type":"Researcher","foaf:name":[{"@value":"Masahiro Nakao"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844222856579","@type":"Researcher","foaf:name":[{"@value":"Toshihiko Ashikari"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844222856580","@type":"Researcher","foaf:name":[{"@value":"Takaaki Kusumi"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00142956"},{"@type":"EISSN","@value":"14321033"}],"prism:publicationName":[{"@value":"European Journal of Biochemistry"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"1997-10","prism:volume":"249","prism:number":"1","prism:startingPage":"45","prism:endingPage":"51"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1111%2Fj.1432-1033.1997.t01-1-00045.x"},{"@id":"https://febs.onlinelibrary.wiley.com/doi/pdf/10.1111/j.1432-1033.1997.t01-1-00045.x"}],"createdAt":"2004-06-23","modifiedAt":"2023-10-31","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390001204326607488","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Transcriptional regulators of flavonoid biosynthesis and their application to flower color modification in Japanese gentians"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001204327278336","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Flower pigment mutations induced by heavy ion beam irradiation in an interspecific hybrid of Torenia"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1111/j.1432-1033.1997.t01-1-00045.x"},{"@type":"CROSSREF","@value":"10.5511/plantbiotechnology.14.0731a_references_DOI_GXBroCO1xYhWGXYaUazIJOZwIXN"},{"@type":"CROSSREF","@value":"10.5511/plantbiotechnology.23.163_references_DOI_GXBroCO1xYhWGXYaUazIJOZwIXN"}]}
