Preliminary crystallographic investigation of allophycocyanin from Porphyra yezoensis in cubic crystal form

摘要

THE phycobilisomes in blue-green algae and red algae are the functional units which absorb and transfer light energy. These supramolecular aggregates are attached on the outer surface of the thylakoid or photosynthetic membrane. Phycobilisomes absorblight in the range of 450--650 nm with an overall quantum efficiency of almost 100%. Electron microscopic studies showed that phycobilisomes consist of two distinct structure parts: the core and the rods.
