Design Notes

This part uses the native cyanobacterial DNA sequence from Anabaena variabilis, with two small but important changes:

1. We removed an EcoRI restriction site by changing the T in position 114 to a C: GAATTC -> GAACTC. 2. We accidentally forgot to include the stop codon in our design. Luckily the BioBrick suffix does include an in-frame TAG stop codon, but if you express the gene directly from this biobrick, you can expect an extra tyrosine at the C terminal of the protein.

Table S1 in [Balskus and Walsh, 2010] contains the gene locus tags and protein accession numbers for the genes in the shinorine biosynthesis gene cluster. Table S4 contains the PCR primers used for cloning the gene cluster.

Ava_3858 corresponds to protein accession number ABA23463.1. The exact DNA sequence can be found in the genome sequence here:

Note that the DNA sequence reported by that link is the reverse complement, since the gene is on the opposite strand in the genome sequence!
