Fig. 1From: Maximizing PHB content in Synechocystis sp. PCC 6803: a new metabolic engineering strategy based on the regulator PirCOverview about important carbon-pathways in Synechocystis and alterations of PPT1 compared to the WT. PPT1 contains a deletion of pirC, as well as an overexpression of phaA and phaB from C. necator. Important enzymes are shown in green. Increased fluxes in PPT1 compared to the WT are indicated by red arrowsBack to article page
