Lay Summary (English)

Lead
Lay summary
The pathway of chlorophyll breakdown has largely been elucidated in recent years. The key reaction being responsible for the loss of green pigment color is catalyzed by the joint action of three protein components, pheophorbide a oxygenase (PAO), red chl catabolite (RCC) forming factor (RFF), and RCC reductase (RCCR). Whereas PAO and RCCR have molecularly been identified, the nature of RFF remains unknown. Open questions exist in respect to the regulation of PAO and the function of RCCR within the chl catabolic pathway. The aim of this project is to address these aspects and to resolve the key reaction of chl breakdown in detail.
