Abstract
Expression of tetanus toxin fragment C is accomplished employing a DNA coding sequence having a (G+C)-content that has been increased in the region from nucleotide 410 to the 3' end of the coding sequence relative to the wild-type DNA sequence. This allows the production of complete mRNA transcripts. Typically the (G+C)-content is increased in the following regions: (i) nucleotides 510-710, (ii) nucleotides 650-850, (iii) nucleotides 800-1100, (iv) nucleotides 900-1200 and (v) nucleotides 1100-1356. These regions in wild-type DNA encompass terminator sequences.
