Ein fluoreszierender Chlorophyll‐Katabolit des Dioxobilin‐Typs als transientes und frühes Zwischenprodukt des Dioxobilin‐Astes des Chlorophyllabbaus in Arabidopsis thaliana

Abstract: Der Chlorophyllabbau findet in hçheren Pflanzen über den "PaO/Phyllobilin"-Weg statt. Dabei werden zwei wichtige Phyllobilin-Typen gebildet, die charakteristischen 1-Formyl-19-oxobiline und die vor kurzem entdeckten 1,19-Dioxobiline.D ie hypothetische Verzweigung ist immer noch unbekannt, an welcher sich die ursprünglich gebildeten [2] was den Wegf ür die weitere strukturgeleitete Erforschung des "PaO/Phyllobilin"-Abbaus des Chlorophylls ebnete.[3] Eine oxidative Spaltung des Chl-Makroringes führt demnach z… Show more

“…In view of a surprising stereochemical diversity observed in natural DNCCs, we suggested an earlier branching‐point in the ‘PaO/phyllobilin’ pathway of Chl‐breakdown . Indeed, a P450‐enzyme catalyzing deformylation of FCCs was identified, which converts FCCs (1‐formyl‐19‐oxobilin‐type or ‘type‐I’ phyllobilins) to corresponding 1,19‐dioxobilin‐type FCCs (DFCCs), hence, opening the pathway to ‘type‐II’ phyllobilins . Under weakly acidic conditions, the latter are indicated to isomerize stereoselectively to corresponding DNCCs (see Fig.…”
