Constraint-based reconstruction and analysis (COBRA) methods have been used for over 20 years to generate genome-scale models of metabolism in biological systems. The COBRA models have been utilized to gain new insights into the biochemical conversions that occur within organisms and allow their survival and proliferation. Using these models, computational biologists can conduct a variety of different analyses such as examining network structures, predicting metabolic capabilities, resolving unexplained experimental observations, generating and testing new hypotheses, assessing the nutritional requirements of a biosystem and approximating its environmental niche, identifying missing enzymatic functions in the annotated genomes, and engineering desired metabolic capabilities in model organisms. This chapter details the protocol for developing curated system-level COBRA models of metabolism in microbes.
约束重建和分析(COBRA)方法已经被使用了 20 多年,以生成生物系统中代谢的基因组规模模型。COBRA 模型被用于深入了解生物体内发生的生化转化,从而使其能够生存和增殖。使用这些模型,计算生物学家可以进行各种不同的分析,如检查网络结构、预测代谢能力、解释未解释的实验观察、生成和测试新假设、评估生物系统的营养需求和近似其环境生态位、识别注释基因组中缺失的酶功能,以及在模式生物中设计所需的代谢能力。本章详细介绍了在微生物中开发精心制作的系统级 COBRA 代谢模型的方案。
