Phycobiliproteins producing activated

Substantial quantities of edible cyanobacteria are produced globally to meet the high demands of both food and pharmaceutical industries. These cyanobacteria contain substantial quantities of phycobiliproteins, of which phycocy-anin, in particular, has various therapeutic effects owing to the linear tetrapyrrole chromophore phycocyanobilin. Cyanobacteria can also synthesize macrocyclic tetrapyrrole corrinoid compounds. However, various edible cyanobacteria contain substantial quantities of inactive pseudo-Bi2 rather than active Bi2- To overcome this nutritional defect of edible cyanobacteria, it is vital to determine the genetic, biochemical, and physiological properties of pseudo-Bi2-...
