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.

With previous basic explorations, we will use a wood vinegar compatible PSB1A2 plasmid backbone, ligated with promoters such as strong promoters (J23104, J23102, etc.), and bpsA sequences to try to express bpsA in K. xylinus while binding to bacterial cellulose membranes.

Strong promoters to improve the bpsA expression

Description

To explore whether more colored fibers could be expressed in K.xylinus. We wanted to express EGFP in K.xylinus using a strong promoter (J23100) as a way to get fluorescent cellulose membranes.
