dehydroquinate synthase (DHQS) generator
Our research has focused on two novel biosynthetic pathways found in two distinct algal species. A pathway ending in the production of two UV-protective compounds, shinorine and mycosporine-glycine, was cloned from Anabaena varibalis. DHQS catalyzes the first step in the pathway, converting sedoheptulose-7-phosphate into dehydroquinate.
This part includes a modified constitutive lac promoter (lacP'), and RBS and the open reading frame of DHQS. This part can be used to express DHQS in E. coli.

Balskus and Walsh, 2010. 
Codon optimised 3-dehydroquinate synthase (DHQS) CDS for use in E.coli as part of the shinorine synthesis gene cluster. By using the IDT codon optimisation tool, St Andrews iGEM 2020 have optimised the GC content of the sequence taken from A.variabilis to improve production efficiency of the final product shinorine. We have further made the part biobrick assembly standard RFC & RFC compatible by removing EcoR1 and SapI restriction sites introduced by this optimisation step. The part should be used alongside the additional optimised parts (BBa_K3634001, BBa_K3634002 and BBa_K3634003) responsible for ultimate conversion of the substrate sedoheptulose 7-phosphate to the final product shinorine.
