Abstract:

The confluence of next generation DNA sequencing and synthesis when combined with the application of concepts such as standardization and modular design has led to the genesis of a new discipline. The nascent field of Synthetic Biology concerns the rational design and construction of genetic circuits, pathways, machines and eventually whole organisms. The immaturity of this field dictates that early research efforts, including this Thesis, describe foundational work towards the creation of tools which make biology more amenable to being engineered. The first part of this Thesis describes an at

Abstract:

Synthetic biology views a complex biological system as an ensemble in the hierarchy of parts, devices, systems, and networks. The practice of using engineering rules such as decoupling and standardization to understand, predict, and re-build novel biological functions from model-driven designed genetic circuits is emphasized. It is one of the top ten technologies that could help solving the current and potential risks in human society. Cyanobacteria have been considered as a promising biological system in conducting oxygenic photosynthesis to convert solar energy into reducing power, which dri

Abstract:

Chinese hamster ovary (CHO) cells are the most commonly used mammalian cell expression system for the industrial production of biotherapeutic recombinant proteins. Mammalian expression systems are a popular choice for the production of complex biopharmaceuticals due to their ability to correctly fold and assemble recombinant proteins and to carry out necessary human-like post-translational modifications. Traditionally, viral promoters are used to drive transgene expression in mammalian cells. This study reports on the investigation of endogenous CHO promoters as potential alternatives to the c

Abstract:

The DNA damage response is a cell-wide response that coordinates repair and cell-cycle progression. Crucial to fidelity of genetic propagation, survival, and apoptosis, dysfunctions in the response are at the root of genome instability syndromes and cancer predisposition in mammalian cells. Within the response lie hubs of coordination, called checkpoints, whose members and organization are ubiquitous amongst eukaryotes. The high conservation of these checkpoints enable the study of their dynamics by proxy via simpler model organisms. We use the budding yeast, Saccharomyces cerevisiae, to study

Enantioselectivity is provided by the use of (1R,2S)-dibutylnorephedrine (1,2-amino alcohol ligand) giving selectivity, in most cases, between 80-96% ee.

Functional expression of different recognition elements or receptors and their coupling to the yeast mating pathway can enable sensing of a variety of ligands.

Abstract:

Higher alcohols synthesized via CO hydrogenation reactions have been a topic of intense study both in industry and academia for over thirty years. A variety of transition metals and promoters have been used in catalysts for this reaction. MoS₂, in particular, is popular due to its low cost, resistance to sulfur poisoning, and ability to selectively produce higher alcohols over hydrocarbons. The bulk material has a rich history in hydrodesulfurization reactions (HDS), and as such, a great deal is known about the material's structure and reactivity. However, even with this deep body of knowledge

Abstract:

The area of methanol synthesis and utilization has been attracting research interests due to its positive impact on the environment and also from energy perspectives. Methanol synthesis from CO<sub>2</sub> hydrogenation not only produces methanol which is a key platform chemical and a clean fuel, but can also recycle CO<sub>2</sub> which is one of the major greenhouse gases causing global warming. As a mobile energy carrier (particularly as a hydrogen carrier), methanol is a versatile molecule which is able to generate H<sub>2</sub> via its decomposition. Catalysis plays a decisive role in the
