"Our efforts revealed that lys encodes the Drosophila homolog of Lysine Ketoglutarate Reductase/Saccharopine Dehydrogenase which is required for the enzymatic degradation of lysine. Furthermore this approach also allowed us to simultaneously survey a large swathe of intermediate metabolism thus demonstrating that Drosophila lysine catabolism is complex and capable of influencing seemingly unrelated metabolic pathways"xsd:string
