Process for the production of spider silk proteins and spider silk protein

摘要

This invention consists of 150 - 420 amino acid residues, is stipulated offers large bottle condition gland supidorointanpaku which is isolated with formula REP CT. REP is the repetitive N terminal derived protein fragment which possesses 80 - 300 amino acid residues. CT is C terminal derived protein fragment which possesses 70 - 120 amino acid residues. The fusion protein where this invention furthermore consists of the first protein fragment and the fusion partner and includes the cutting medicine recognition region the second protein fragment which are large bottle condition gland supidorointanpaku and is isolated is offered. The first protein fragment is connected to the fusion partner via the cutting medicine recognition region. In addition as for this invention, production method of large bottle condition gland supidorointanpaku and its polymer is offered.
