Figure 5From: Complementation of a phycocyanin-bilin lyase from Synechocystis sp. PCC 6803 with a nucleomorph-encoded open reading frame from the cryptophyte Guillardia thetaProteolytic digestion of phycobilisomes. (A) Digestion of phycobilisomes with formic acid. The arrow indicates the resulting fragment after Zn2+ stain at 2.78 kDa. There are also several signals at 17–20 kDa which refer to the unaffected α-subunit of phycocyanin and the α- and β-subunit of allophycocyanin.Back to article page
