The modeling of rates of biochemical reactions-fluxes-in metabolic networks is widely used for both basic biological research and biotechnological applications. A number of different modeling methods have been developed to estimate and predict fluxes, including kinetic and constraint-based (Metabolic Flux Analysis and flux balance analysis) approaches. Although different resources exist for teaching these methods individually, to-date no resources have been developed to teach these approaches in an integrative way that equips learners with an understanding of each modeling paradigm, how they relate to one another, and the information that can be gleaned from each. We have developed a series of modeling simulations in Python to teach kinetic modeling, metabolic control analysis, 13C-metabolic flux analysis, and flux balance analysis. These simulations are presented in a series of interactive notebooks with guided lesson plans and associated lecture notes. Learners assimilate key principles using models of simple metabolic networks by running simulations, generating and using data, and making and validating predictions about the effects of modifying model parameters. We used these simulations as the hands-on computer laboratory component of a four-day metabolic modeling workshop and participant survey results showed improvements in learners' self-assessed competence and confidence in understanding and applying metabolic modeling techniques after having attended the workshop. The resources provided can be incorporated in their entirety or individually into courses and workshops on bioengineering and metabolic modeling at the undergraduate, graduate, or postgraduate level.
生化反应速率(通量)在代谢网络中的建模被广泛应用于基础生物学研究和生物技术应用。已经开发了许多不同的建模方法来估计和预测通量,包括基于动力学和约束的方法(代谢通量分析和通量平衡分析)。尽管存在用于单独教授这些方法的不同资源,但迄今为止,还没有开发出用于以综合方式教授这些方法的资源,这些资源使学习者能够理解每个建模范例、它们之间的关系以及从每个范例中可以获得的信息。我们使用 Python 开发了一系列建模模拟来教授动力学建模、代谢控制分析、13C-代谢通量分析和通量平衡分析。这些模拟以一系列具有指导课程计划和相关讲义的交互式笔记本呈现。学习者通过运行模拟、生成和使用数据以及对修改模型参数的效果进行预测来吸收有关简单代谢网络模型的关键原理。我们将这些模拟用作为期四天的代谢建模研讨会的实践计算机实验室部分,参与者调查结果表明,参加研讨会后,学习者在理解和应用代谢建模技术方面的自我评估能力和信心有所提高。提供的资源可以全部或单独纳入本科、研究生或研究生水平的生物工程和代谢建模课程和研讨会中。
