Figure 2From: Agent-based simulation of reactions in the crowded and structured intracellular environment: Influence of mobility and location of the reactantsMetabolic channeling and scaffolds in signal transduction. (a) Metabolic channeling in contrast to unconnected metabolic reactions with unbound enzymes [24]. (b) Signal transduction through a localized scaffold versus unbound signaling components that can also activate other pathways (crosstalk) - here Kss1 in addition to Fus3 in yeast Saccharomyces cerevisiae [27].Back to article page
