Genome-scale metabolic models have proven to be valuable for predicting organism phenotypes from genotypes. Yet efforts to develop new models are failing to keep pace with genome sequencing. To address this problem, we introduce the Model SEED, a web-based resource for high-throughput generation, optimization and analysis of genome-scale metabolic models. The Model SEED integrates existing methods and introduces techniques to automate nearly every step of this process, taking approximately 48 h to reconstruct a metabolic model from an assembled genome sequence. We apply this resource to generate 130 genome-scale metabolic models representing a taxonomically diverse set of bacteria. Twenty-two of the models were validated against available gene essentiality and Biolog data, with the average model accuracy determined to be 66% before optimization and 87% after optimization.
基因组规模代谢模型已被证明可用于从基因型预测生物体表型。然而,开发新模型的努力未能跟上基因组测序的步伐。为了解决这个问题,我们引入了 Model SEED,这是一个基于网络的资源,用于高通量生成、优化和分析基因组规模代谢模型。Model SEED 集成了现有方法,并引入了技术,几乎可以自动执行该过程的每一步,从组装的基因组序列重建代谢模型大约需要 48 小时。我们应用该资源生成了 130 个代表细菌分类多样化的基因组规模代谢模型。其中 22 个模型与现有的基因必需性和 Biolog 数据进行了验证,在优化之前,平均模型准确性为 66%,在优化之后为 87%。
