| Abstract |
Vssilk 5 is a gene encoding a component protein of the silk produced by the larvae of the yellow hornet (Vespa simillima, Vespinae, Vespidae). In this study, we deduced the complete cDNA sequence of Vssilk 5. It was found that 2 silk proteins, Vssilk 5 N and Vssilk 5 C, in the cocoon of the yellow hornet are both encoded by the Vssilk 5 gene. Vssilk 5 N and 5 C are the N- and C-terminal regions, respectively, of the Vssilk 5 pro-protein (Vssilk 5p). The complete amino acid sequences of Vssilk 5 N and Vssilk 5 C were deduced. Although a non-repetitive amino acid sequence and coiled-coil structure are properties common to the major components of silk proteins produced by the larvae of the social superfamilies Apoidea and Vespoidea of the Apocrita, nearly the entire sequence of Vssilk 5 C consisted of a repeated sequence of amino acids, and the calculated coiled-coil probability for this protein was low. Vssilk 5 N is a protein without a repetitive amino acid sequence and has a low coiled-coil probability. Moreover, we found a water soluble protein, Vssilk 5S that is likely segmented from Vssilk 5 C and contains an N-terminal sequence identical to that of Vssilk 5 C.
