Part:BBa_K814002

dehydroquinate O-methyltrasferase (O-MT) 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. Dehydroquinate O-methyltransferase (O-MT) catalyzes the second step in this pathway, converting dehydroquinate to 4-deoxygadusol.

This part includes a modified constitutive lac promoter (lacPmod), and RBS and the open reading frame of O-MT. This part can be used to express O-MT in E. coli.

BBa_K3634001

Codon optimised O-methyltransferase (O-MT) 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[10] & RFC[1000] compatible by removing XbaI and SapI restriction sites introduced by this optimisation step. The part should be used alongside the additional optimised parts (BBa_K3634000, BBa_K3634002 and BBa_K3634003) responsible for the ultimate conversion of the substrate sedoheptulose 7-phosphate to the final product shinorine.
