从β衍生的最小的CNBr片段。聚球藻亚基。用360 MHz~1H核磁共振波谱对蓝色七肽6301C-藻蓝蛋白进行了研究。七肽部分是独立合成的，并用于比较光谱分析。这些研究导致了多肽连接的藻蓝胆素的结构的完整归属和硫醚发色团-多肽连接的性质的阐明。
The smallest CNBr fragment derived from the .beta. subunit of Synechococcus sp. 6301 C-phycocyanin, the blue heptapeptide, was investigated by 360-MHz 1H NMR spectroscopy. The peptide portion, heptapeptide, was synthesized independently and used in comparative spectroscopic analysis. These studies led to complete assignment of the structure of the peptide-linked phycocyanobilin and elucidation of the nature of the thioether chromophore-peptide linkage.
