Evolutionary optimization of metabolic pathways. Theoretical reconstruction of the stoichiometry of ATP and NADH producing systemsO Ebenhöh
Humboldt Universitat zu Berlin, Institut für Biologie Theoretische Biophysik, Invalidenstrasse 42, D 10115 Berlin, Germany
Bull Math Biol 63:21-55. 2001..A distance measure and a measure for the internal ordering of reactions are introduced to study differences and similarities in the stoichiometries of metabolic pathways...
Structural analysis of expressed metabolic subnetworksOliver Ebenhöh
Institute for Biology, Humboldt University Berlin, 10115 Berlin, Germany
Genome Inform 17:163-72. 2006..These findings indicate that gene regulation increases the range of essential compounds that can be obtained from the available nutrients, while minimising the number of expressed enzymes and therefore the burden of protein synthesis...
