Fig. 3From: Improving the active expression of transglutaminase in Streptomyces lividans by promoter engineering and codon optimizationCodon optimization of S. hygroscopicus WSH03-13 TGase. The Greek numerals (left side) indicated the sequence type of TGase: I: original sequence of S. hygroscopicus TGase ORF; II: Streptomyces preferred gene sequence of the TGase ORF; III: amino acid sequence of the TGase ORF. The grey shadows and “---” indicated the mutated positions and invariant positions. The numbers (right side) indicated the nucleotide sequencesBack to article page
