Biosynthesis of phycobiliproteins. Incorporation of biliverdin into phycocyanin of the red alga Cyanidium caldarium. 1984

S B Brown, and J A Holroyd, and D I Vernon

14C-labelled biliverdin IX alpha was administered to cultures of Cyanidium caldarium that were actively synthesizing photosynthetic pigments in the light. Between 9 and 12% of the phycobiliprotein chromophore produced in such cultures was derived from exogenous biliverdin. These results demonstrate that biliverdin is an intermediate in the biosynthesis of phycobiliproteins.

UI	MeSH Term	Description	Entries

D000461	Rhodophyta	Red algae whose color results from predominace of the red pigment (PHYCOERYTHRIN). However, if this pigment is destroyed, the algae can appear purple, brown, green, or yellow. Two important substances found in the cell walls of red algae are AGAR and CARRAGEENAN. Some rhodophyta are notable SEAWEED (macroalgae).	Algae, Red,Red Algae
