Pheide
WebNov 26, 2013 · Thus, rather than being solely phototoxic, Pheide has been speculated to act as a signaling molecule that may be exported from the chloroplast, as suggested for Mg-protoporphyrin IX, the first intermediate of the Chl branch of the tetrapyrrole biosynthesis pathway (Mochizuki and others 2001; Hirashima and others 2009 ). WebJun 19, 1998 · The conversion of Pheide a to a primary blue fluorescent catabolite (pFCC; Ref. 12) requires the joint action of PaO and a soluble stroma-located enzyme that reduces an intermediary red catabolite (RCC; Ref. 13) to pFCC (Fig. 1, Ref. 14 ). Both PaO and RCC reductase require reduced ferredoxin (Fd) as reductant.
