Special Issue "Enzyme Engineering: From Chemically Induced Modifications to Genetic Code Expansion"
Deadline for manuscript submissions: 31 March 2021.
Interests: protein engineering, chemical biology, proteomics and drug discovery
Interests: protein chemistry, protein engineering and drug discovery
Enzyme engineering has become extremely important for biocatalytic processes, which is observed by the amount of research that has been dedicated to this field in the past decade. This interest is due to the intrinsic features of enzymes and their advantages over chemical catalysts such as high productivity, specificity, and catalytic efficiency, but it is also faced with high cost and low stability issues. These drawbacks have propelled the development of several methods to tackle these problems while also avoiding the cost and waste associated with single-use and throwaway practices. Traditional methods of enzyme engineering have enabled the production of stable and highly efficient enzymes as well as entirely new functionalities, but they have also started to concede space to more advanced approaches. Recent efforts have focused on induced chemical modifications and genetic code expansion to install new catalytic modalities, expand acceptable substrates, and increase thermostability amongst other features. This Special Issue aims to cover the progress and trends in traditional enzyme engineering, new chemical methods to modify and modulate enzyme activity and structure, genetic code expansion by insertion of noncannocial amino acids (ncAA), and other strategies to develop innovative biocatalysts.

Abstract: In hydraulic fracturing, the fracturing fluid is used to transport the proppant into the fracturing operation reservoir. The higher hydraulic fluid's viscosity is vital in fracturing the reservoir and suspension of sand and proppants. The thickness of hydraulic fracturing fluid increased through the addition of guar polymers. After the fracturing, the fluid viscosity should be quickly dropped for enhancement of oil and gas recovery. The enzyme breakers are used to break the fracturing fluid completely by degrading the guar polymer. Different types of the enzyme have been isolated and employed to reduce the hydraulic fluid's viscosity in the oil and gas industry at high temperatures. Thermostability remains the major obstacle for the use of enzyme breakers in oil application. The enzyme engineering approaches such as direct evolution, rational design, and the latest machine learning have a great potential to increase enzyme breakers' thermostability against high temperatures. This prospect article will describe a brief overview of recent advanced enzyme molecular engineering technologies and how these technologies could be used to enhance the thermostability of enzyme breakers in oil applications.
