[A study of periodicity in the primary structure of spidroin 1 and spidroin 2 from spiders belonging to various species].
Sequences of spidroin 1 and 2 from spiders belonging to various species were analyzed by Fourier analysis. Specific periodical patterns were found in various segments of the sequences. These characteristic periodicities vary within the same proteins as well as between spidroin 1 and spidroin 2 sequences. It is possible that alterations in periodicity help to recognize contact sites between the molecules. Spidroins of 2 type have similar sequence structure consisting of four parts with a particular periodical pattern. These parts are a constant C-terminal part, a long-periodical part, a short-periodical part, and a constant N-terminal part.
