Preliminary Studies on the 43-kD Protein in Phycobilisomes of Cyanobacterium Anacystis nidulans R-2
蓝细菌Anacystis nidulans R-2 藻胆体中43 kD蛋白细胞定位的初步研究

Phycobilisomes, containing a 43-kD protein, were isolated from Anacystis nidulans R-2. Dissociated phycobilisomes exhibited FNR diaphorase activity. Western blotting showed that the 43-kD protein could react with antibodies raised against Fd:NADP+ oxidoreductase. Analysis by Triton X-114 phase-partitioning indicated that the 43-kD protein could not enter into the detergent phase. Partial dissociation of phycobilisomes revealed no 43-kD protein in the fractions mainly containing rod components.
