Abstract:
:Repetitious gene cassettes that encode the consensus decapeptide repeat of Mytilus edulis bioadhesive protein were designed, constructed, and expressed in Escherichia coli. The bioadhesive precursor (BP) with a relative molecular mass of 25,000 was expressed from one 600-bp gene at levels approaching 60% of total cell protein in strains employing T7 RNA polymerase for induction and carrying a repetitious gene comprised of a 30-bp unit repeat that accounts for E. coli codon bias. BP forms intracellular inclusions and yet methionine was processed from the N-terminus of the purified protein, as shown by amino acid composition and N-terminal sequencing, to give an authentic consensus precursor protein.
