Design considerations

We performed Chlamydomonas reinhardtii's domestication for GS sequence. This process includes a reduction of the GC% content to make the sequence suitable for commercial synthesis while maintaining it high enough to fit Chlamydomonas reinhardtii's codon usage. This was done using our optimizing software (see AlgaGenix's wiki for additional information). Moreover, recognition sites for BbsI and BsaI were eliminated, changing said codons with synonymous ones. Besides, we also added an intron to perform what is known as intron-mediated enhancement (IME), which studies show aids with stable high-level expression of a foreign gene (Lumbreras et al., 1998) AlgaGenix’s Level 1s are designed to have the same structure and not having to build different pieces with different positions for each gene.
