摘要
Background: A 代謝 is a complex 網絡 of chemical reactions. This 網絡 synthesizes multiple small precursor molecules of biomass from chemicals that occur in the environment. The metabolic 網絡 of any one organism is encoded by a metabolic genotype, defined as the set of enzyme-coding genes whose products catalyze the 網絡's reactions. Each metabolic genotype has a metabolic phenotype. We define this metabolic phenotype as the spectrum of different sources of a chemical element that a 代謝 can use to synthesize biomass. We here focus on the element sulfur. We study properties of the space of all possible metabolic genotypes in sulfur 代謝 by analyzing sources. Results: We show that metabolic genotypes with the same phenotype form large connected genotype 網絡s 網絡s of metabolic 網絡s - that extend far through
