Nanoscale Biocatalysis

Nanomaterials for Biocatalysis explains the fundamental design concepts and emerging applications of nanoscale biocatalysts, such as bioconversions, bioelectronics, biosensors, biocomputing and therapeutic applications. Nano-biocatalysts refers to the incorporation of enzymes into nanomaterials. These enzyme-enhanced nanocarriers have many advantages, including low mass transfer limitation, high enzyme capacity, better stabilization, and the formation of single-enzyme nanoparticles. Smart nanocontainers have been developed for the smart release of their embedded active substances. These smart releases can be obtained by using smart coatings as their outer nanoshells. In addition, these nanocontainers could protect the enzymes from chemical or metabolic alterations on their delivering pathways towards the target. This is an important reference source for materials scientists and chemical engineers who want to know more about how nanomaterials are being used for biocatalysis applications. Explains the major fabrication techniques and applications of nanobiocatalysts Shows how nanobiocatalysts are used in a variety of environmental and biomedical sectors Assesses the major challenges associated with the widespread manufacture of nanobiocatalysts

Nanobiocatalysis has rapidly developed into a subarea of enzyme biotechnology. It combines the advances in nanotechnology that have generated nanoscale materials of different sizes, shapes, and physicochemical properties, and the excellent characteristics of biocatalysts into an innovative technology. This book provides an overview of the various relations between nanotechnology and biocatalysis. It discusses the fabrication and application of nanomaterials for the immobilization of enzymes used in the sustainable production of goods and chemicals. Nanosupports have several advantages compared with bulk solid materials because of their high surface area, which results in a significantly reduced mass transfer limitation and comparatively high enzyme loading. These characteristics are also of great use for applications in the fields of enzymatic biosensors, biofuel cells, bioelectronics, and photoelectrochemical analyte detection, where conductive nanomaterials improve the rate of electron transfer. The book also presents an overview of nanotoxicology and covers nanostructured enzyme catalysis in organic solvents and its potential application for biodiesel production, probing of enzymatic activity, and identification of enzyme functions of inorganic nanoparticles as enzyme mimics.

Nanoscale science and engineering, which deal with size-dependent properties and phenomenon at nanometer scale, are unveiling new mechanisms that scientists must rely on heavily at the present time to achieve efficient and sustainable chemical processing technologies. In Nanoscale Biocatalysis: Methods and Protocols, expert researchers in the field contribute detailed methodologies and procedures that have been developed from recent research in this burgeoning area of nanoscale technology-enabled biocatalysis. The volume opens with concepts in preparing unique and dynamic protein structures for biocatalysis, then moves on to cover methods for preparation of enzyme assembles or complexes that maintain molecular-like Brownian mobility, the development of protein-nanostructure complexes using carbon nanotubes (CNTs) and nanoparticles, as well as methodologies that have great potential for scale-up preparation of nano-structured biocatalysts. Written in the highly successful Methods in Molecular Biology series format, chapters include brief introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and vital tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Nanoscale Biocatalysis: Methods and Protocols is an ideal guide to the new wave of development in nearly all the major areas of science and engineering brought about by this fascinating and greatly promising area of study.

This volume provides an insight into the future strategies for commercial biocatalysis with a focus on sustainable technologies, together with chemoenzymatic and biotechnological approaches to synthesize various types of approved and new active pharmaceutical ingredients (APIs) via proven and latest synthetic routes using single-step biocatalytic or enzyme cascade reactions. Many of these drugs act as enzyme inhibitors, as discussed in a chapter with a variety of examples. The targeted enzymes are involved in diseases such as different cancers, metastatic and infectious diseases, osteoporosis, and cardiovascular disorders. The biocatalysts employed for API synthesis include hydrolytic enzymes, alcohol dehydrogenases, laccases, imine reductases, reductive aminases, peroxygenases, cytochrome P450 enzymes, polyketide synthases, transaminases, and halogenases. Many of them have been improved with respect to their properties by engineering methods. The book discusses the syntheses of drugs, including alkaloids and antibiotics, non-ribosomal peptides, antimalarial and antidiabetic drugs, prenylated xanthones, antioxidants, and many important (chiral) intermediates required for the synthesis of pharmaceuticals.

Marine bioprospecting is a highly topical subject - in both applied and basic research - but, as yet, the marine ecosystem is a relatively unexplored source of natural bioactive substances with potential therapeutic activity. This book addresses the use of marine enzymes in biocatalysis through a series of chapters from leading scientists within academic and industrial fields. Biocatalytic processes can take advantage of the habitat-related properties of marine enzymes, such as salt tolerance, hyperthermostability, barophilicity, cold adaptivity, and so on, whilst also taking into consideration substrate specificity and affinity. These evolved properties are linked to the metabolic functions of the enzymes and to the ecological aspects of the natural source. New properties can also be discovered at the molecular level of catalysis, particularly concerning the stereochemical characteristics of products.Marine enzymes for biocatalysis initially examines the nature and level of interest in marine biological diversity, and outlines the fundamentals of biocatalysis. It goes on to detail sources of marine enzymes, and to analyse examples from both chemical and stereochemical viewpoints of catalysis, including microbial enzymes and animal or plant sources. The book goes on to explore the future potential of marine bioprospecting in biocatalysis. Compiles studies from leading scientists in a direct and accessible format. Includes practical descriptions of results, adding further details not often covered in formal articles Takes a molecular view which fully explains the enzymatic aspects of reactions, particularly regarding biocatalytic characteristics and descriptions of bioprocesses Selects examples of chemical and stereochemical aspects of enzymatic action with respect to known terrestrial counterparts
