The putative operon consists of four genes, bcsA, bcsB, bcsC and bcsD. It encodes membrane-associated proteins can catalyse extracellular Bacterial Cellulose synthesis in vivo. Once the bcsABCD operon expression is triggered, BcsA and BcsB proteins form the BcsAB complex, which binds its substrate, UDP-glucose, at an intracellular glycosyltransferase (GT) domain.

This part codes for the CcpAx protein, an assisting protein in cellulose biosynthesis in Bacteria. It is codon optimised for Flavobacterium johnsoniae UW101



Description


ccpAx encodes for a cellulose complementing factor. The function of this protein is not yet understood.



The Bacterial Bcs Operon


The putative operon consists of four genes, bcsA, bcsB, bcsC and bcsD. It encodes membrane-associated proteins can catalyse extracellular Bacterial Cellulose synthesis in vivo. Once the bcsABCD operon expression is triggered, BcsA and BcsB proteins form the BcsAB complex, which binds its substrate, UDP-glucose, at an intracellular glycosyltransferase (GT) domain. This complec is the active core of the cellulose synthase. This is followed by the secretion of BC fibres through pores and passageways formed by BcsC and BcsD proteins. Co expression with Cmcax and CcpAx have shown increased production. The cellulose synthase, BcsC, BcsD, Cmcax, and CcpAx are the biocatalysts of UDP-glucose transformation to cellulose. Two main applications of cellulose in biosciences are scaffolds for tissue engineering and generally in biomedicine.

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.


SOURCE OF THIS PART


The nucleotide sequences of the bacterial cellulose operon come from the strain Komagataeibacter xylinus and GenBank database (Acc.No.X54676.1). K.xylinus is a member of the acetic acid bacteria, a group of Gram-negative aerobic bacteria that produce acetic acid during fermentation.
