The pathways of central metabolism provide the metabolic connections between the catabolic (degradative) and anabolic (biosynthetic) routes in all living organisms. In hyperthermophilic Archaea, we have discovered a promiscuous central metabolic pathway that catabolizes a variety of sugars using a single set of enzymes. This article explores the structural basis of this promiscuity in enzymes that have to maintain their integrity at temperatures approaching 100°C.
