Rhodotorulic acid is the smallest of the 2,5-diketopiperazine family of hydroxamate siderophores which are high-affinity chelating agents for ferric iron, produced by bacterial and fungal phytopathogens for scavenging iron from the environment. It is a tetradentate ligand, meaning it binds one iron atom in four locations (two hydroxamate and two lactam moieties), and forms Fe2(siderophore)3 complexes to fulfill an octahedral coordination for iron.

  • ロドトルル酸(Rhodotorulic acid)とはシデロホアの一つの有機化合物である。ヒドロキサム酸シデロホアの2,5-ジケトピペラジンファミリーで最も小さい化合物である 。植物病原性の細菌や真菌によって分泌される 。鉄との結合部を4カ所、2個のヒドロキサム酸基と2個のケトン基を持ち、すなわち4座の鉄キレート剤である。最大個数まで鉄と結合した際、Fe2(ロドトルル酸)3 複合体を形成し、八面体構造となる。ロドトルル酸は担子菌類酵母によって産生され 、Botrytis cinereaの胞子の発芽を阻害する。酵母の一種R. glutinis はロドトルル酸の分泌により生物的防除剤として有用であり 、イプロジオン耐性B. cinerea によるリンゴへの疾病予防に有効である。 (ja)

  • Rhodotorulic acid is the smallest of the 2,5-diketopiperazine family of hydroxamate siderophores which are high-affinity chelating agents for ferric iron, produced by bacterial and fungal phytopathogens for scavenging iron from the environment. It is a tetradentate ligand, meaning it binds one iron atom in four locations (two hydroxamate and two lactam moieties), and forms Fe2(siderophore)3 complexes to fulfill an octahedral coordination for iron. Rhodotorulic acid occurs in basidiomycetous yeasts and was found to retard the spore germination of the fungus Botrytis cinerea. In combination with yeast R. glutinis it was found to be effective in the biocontrol of iprodione-resistant B. cinerea of apple wounds caused by the disease. (en)
