Figure 2: Overview of polyhydroxybutyrate (PHB) metabolism in R. eutropha H16.
From: Genome sequence of the bioplastic-producing “Knallgas” bacterium Ralstonia eutropha H16
The light gray field represents a PHB storage granule inside a bacterial cell. Arrows indicate the major enzymatic reactions of PHB synthesis and degradation. The boxes, circles and other shapes symbolize the enzymes and proteins involved directly in PHB metabolism, whereas stacked symbols indicate the existence of multiple alleles in the genome. Symbols outlined in blue represent proteins known to be associated with the PHB granule. See text for details.
