Metabolic Engineering has been likened to traffic management, where carbon and other atoms are the people, metabolites are their locations, and enzymes are the vehicles that transport them. In this free online introductory course in Metabolic Engineering, you will learn how modifications of specific biochemical reactions of an organism can enhance the production of desired metabolites via recombinant DNA technology. You will discover how to identify biochemical reaction targets, and then apply molecular biology techniques for enzyme amplification and modifications. The steps of microbial cell engineering, including host selection, parts assembly, etc., as well as the important metabolites and chemical end products, will be studied. You will examine important research concepts like Biofundry, vital tools like CRISPR Cas9, and obtain the preliminary skills for their application. The subject will outline the major aspects, including cell physiology, fluxomics, and synthetic biology. Also, the basic research techniques in metabolomics and metabolic flux analysis will be disclosed. You will discover why metabolic engineering is the method for in vitro evolution, and, acquire the skills for its application in evolutionary systems. Study how to use bioengineering processes to up-regulate pathways of interest via the biological system’s machinery for maximal product yields. Discover the enzyme specificity, and pathway inhibition mechanisms in microbial engineering, plus, how you can enable the synthetic components, and activate the expression regulators. You will discern the focal theme and crucial steps, and see how metabolic engineering can enhance cost-effective models development via the functional schemes for commercial process support.

Next, the complex network of enzymatic reactions, such as the chemical responses and regulatory interactions that occur during cell metabolism will be highlighted. You will learn how to identify metabolite-centric and enzyme-centric networks, and adopt seed tests for identifying the compounds that are synthesized from the environment. The use of the Biochemical Network Integrated Computational Explorer (BNICE) for computer-aided biochemical pathways analysis will be proposed. Likewise, the chemical structure of substrates and products, and the enzymatic rules used for enzyme classification (EC) systems will also be considered. Study how you can determine the complexity and diversity of the metabolic maps for feasible and observable reactions, and the advanced systems for engineering a production phenotype via the metabolic flux analysis (MFA). Topics on the overarching principles of metabolism of living systems will cover enzyme catalysis, energy harvesting, coupled reactions, as well as energy transduction to ATP via transmembrane ion gradients. The frameworks of metabolism will consider the four distinct reactions which determine the primary functions of the overall cell synthesizing process. Then, you will examine the dynamic timescale of metabolic reactions through allosteric control and mutational variations. Additionally, the two major processes of cellular transport will be dissected. Then, several important concepts, including, facilitated diffusion, carrier-mediated, ion-coupled, and ATP binding cassette (ABC) transport systems, etc., will be presented.

Finally, the topic on group translocation will highlight the Phosphoenolpyruvate-sugar phosphotranferase systems (PTS) for solute transportation and phosphorylation. Learn about transporter engineering and its benefit in substrate adsorption and volumetric productivity. Study the three types of hexose monophosphates that aid the entrance of sugars into the glycolytic pathway, and the reactions (glycolysis) that facilitate their conversion into pyruvic acid. Similarly, the adenosine monophosphate pathway (AMP), pentose phosphate pathway (PPP), and Entener Doudoroff (ED) pathway, will be discussed. Likewise, the proton motive force (PMF), which drives the electrochemical proton gradient in oxidative phosphorylation will be explained. Then, the stoichiometry of oxidative phosphorylation (also known as P/O ratio) will be outlined. What are metabolic fluxes and flux maps? What is the interrelatedness of metabolic engineering and genetic engineering? This course will examine these subjects and consider the facts that surround them. Whether you are a student, job seeker or young scientist seeking a career path in computational biology, genetic engineering or metabolic engineering, by completing this course, you will acquire the basic skills of microbial engineering and recombinant DNA technology. Your proficiency in this subject will consequently lead to improvements in the development of natural metabolites and products for the pharmaceutical, bioenergy, biochemical or biotechnological industries.
