Functional structure and organization of carbon metabolism in Pseudomonas putida. The metabolic network structure is organized as a “bow tie.” The bow tie is decomposed into three modules; i.e., the catabolic and anabolic reactions are organized as fan-in and fan-out parts of the bow tie, and the knot part of the bow tie is comprised of the 12 biomass precursor metabolites that form the central carbon metabolism.
