Preliminary Study on the Primary Structure of Dragline Fibroin from the Spider Araneus ventrocosus.
The amino acid composition of the dragline fibroin from the spider fibroin of the spider Araneus ventrocosus was analysed and compared with that of the fibroins from different species of spiders. By means of partial acid hydrolysis and high performance liquid chromatography, several peptide fragments of the dragline fibroin were purified. The amino acid sequence analysis showed the sequences of these peptides to be different from that of the fibroin from the spider Nephila clavipes except for one common fragment with the sequence of GYGPG.
