Expressing PPTase to activate bpsA
C. glutamicum 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).However,in K.xylinus,there is no pcpS exist.Thus,we need to build a bpsA-pcpS fragment so that bpsA can be activated to catalyze the reaction.
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.
