pHimarEm1+TUs of BcsA,B,C,D

Usage and Biology

The pMORPHÆ plasmid, consists of the pHimarEm1 vector (BBa_K3520009) containing the transcriptional units of the bcs operon’s genes (A. xylinous). More specifically, this composite vector was designed in order to permanently insert these genes into the Flavobacterium’s genome, as to produce cellulose. This plasmid was made by connecting the parts BBa_K3520013, BBa_K3520014, BBa_K3520015, BBa_K3520016, designed by iGEM Athens.

The present plasmid is used to insert the Bcs operon genes (X54676.1) to a bacterium of the Flavobacterium genus through conjugation using an Escherichia coli strain for conjugation. Each gene has its own transcriptional unit that will allow their constitutive expression. These genes will all intergrated into the genome of the target Flavobacterium with the help of the Mariner transposon and then the Cellulose is produced by the recombinant bacteria.

Athens 2020

The current part is designed by iGEM Athens 2020 team during the project MORPHÆ. In this project, Flavobacteria were used to produce a non-cellular structurally coloured biomaterial which would require the secretion of a biomolecule that Flavobacteria do not normally secrete. Our hypothesis is that the formed matrix will have a structure similar to that of the biofilm and thus, it will provide the material with macroscopically the same colouration properties as the biofilm.
