additional information | construction of chimeric proteins by RIBS in vivo DNA shuffling of the feruloyl esterase genes of strains Streptomyces cinnamoneus NBRC 12852 and Streptomyces cinnamoneus TH-2. A domain comprised of residues 140 to 154 is crucial for the catalytic activity of isoform EstA | Streptomyces cinnamoneus |
additional information | construction of chimeric proteins by RIBS in vivo DNA shuffling of the feruloyl esterase genes of strains Streptomyces cinnamoneus NBRC 12852 and Streptomyces cinnamoneus TH-2. insertion of residues Pro and Gly between residues Asn-152 and Ala-153, i.e. mutant 18PG, leads to increased activity with substrates methyl ferulate and methyl sinapinate | Streptomyces sp. TH-2 |
