Bacterial laccase from Bacillus sp. - codon optimized
Description
This is the codon-optimized coding sequence of laccase (cotA) from Bacillus sp. HR03. The enzyme has been expressed in E. coli BL21(DE3) and its properties have been discussed by Mohammadian, Fathi-Roudsari, Mollania, Badoei-Dalfard, and Khajeh (2010). It was shown to have the highest activity when expressed at 18℃ and put at 70℃ (Mohammadian et al., 2010).
As an oxidase, laccase has been used to catalyze dye synthesis from plant-derived pigment precursors (Jeon et al., 2010). In the study, 15 phenols and 120 combinations were studied. Three combinations, gallic acid and syringic acid, catechin and catechol, and ferulic acid and syringic acid, were further studied as they were oxidized into brown, black, and red materials, respectively (Jeon et al., 2010). Inspired by the principle of synthetic dyes, it was hypothesized that such combinations could be used as an alternative to direct dying with pigments.
The complete coding sequence for laccase (cotA) from Bacillus sp. HR03 has been included in the GenBank database (reference code: FJ663050.1). iGEM20_Shanghai_SFLS_SPBS optimized the codons based on that sequence, constructed the plasmid pET28b-T7-laccase, and tested the expression and activity of laccase.
