BpsA stands for the Blue-pigment indigoidine synthetase gene.Itself is derived from Streptomyces lavendulae and is used in the synthesis of indigo. It can only be activated from inative apo-form to the active holo-bpsA by the addition of CoA to its PCP, catalyzed by PPTase, which synthesizes two molecules of glutamine into one molecule of indigo. Corynebacterium glutamicum is usually used to express bpsA for high indigo production.

Corynebacterium glutamicum is the ideal host for the expression of bpsA to achieve high indigoidine production, because it carries strong fluxes of L-glutamate, a precursor of L-glutamine and L-glutamine is the substrate of the indioigdine synthetase. Meanwhile, C. glutamicum also has the native pcpS gene, which expresses PPTase(4'-phosphopantetheinyl transferase). The PPTase is of great significance because it converts the apo-form of the BpsA into its active holo-form by attaching coenzyme A to the peptide carrier domain (PCP).

Using strong promoters to improve the bpsA expression

Description

BpsA stands for the blue pigment indigoidine synthetase gene, encoding a single module type non-ribosomal peptide synthetase called BpsA. Indigoidine synthetase can synthesize two molecules of glutamine into one molecule of indigoidine. Itself is derived from Streptomyces lavendulae.

Corynebacterium glutamicum is the ideal host for the expression of bpsA to achieve high indigoidine production, because it carries strong fluxes of L-glutamate, a precursor of L-glutamine and L-glutamine is the substrate of the indioigdine synthetase. Meanwhile, C. glutamicum also has the native pcpS gene, which expresses PPTase(4'-phosphopantetheinyl transferase). The PPTase is of great significance because it converts the apo-form of the BpsA into its active holo-form by attaching coenzyme A to the peptide carrier domain (PCP).

In this project first we will obtain indigoidine, the chemical structure of which is 5,5-diamino-4,4-dihydroxy-3,3-diazadiphenoquinone-(2,2), by introducing pEKEX2 plasmid backbone ligated with bpsA, into C. glutamicum. In the next step, we would genetically modify Komagataeibacter xylinus and introduce PSB1A2 plasmid backbone ligated with bpsA and pcpS for one-step synthesis of colored fibers, and also codon optimize the bpsA and pcpS coding sequences to meet our needs.


Experiment

Promoters

We chose to use the Anderson family promoter, first, because it is compatible with K.xylinus, and there is enough references reporting that these promoters have been tested in several of bacteria such as G. xylinus 700178, G. hansenii 53582, and K. rhaeticus iGEM.Then we selected three of the strong promoters:J23100,J23104 and J23119.Here we choose J23100 promoter to test its performance.We linked it to bpsA-pcpS in the hope that colorful cellulose could be expressed.

Expression of bpsA in K. xylinus

Because K. xylinus does not have the native PPTase that is necessary for activating apo-form of indigoidine synthase into its active holo-form by adding coenzyme A to the peptide carrier domain (PCP), we need to transfect the target gene both bpsA and pcpS (encoding PPTase)into K. xylinus using pSB1A2 as a plasmid vector, and synthesize indigoidine fibers using K. xylinus which is capable of producing cellulose in high yield.With previous basic explorations, we will use PSB1A2 plasmid backbone, ligated with promoters such as strong promoters (J23104,J23100,J23119 etc.), and CDS sequences to express bpsA and pcpS in K. xylinus while binding to bacterial cellulose membranes.
