Transaminases (TAs) are one of the most promising biocatalysts in organic synthesis for the preparation of chiral amino compounds. The concise reaction, excellent enantioselectivity, environmental friendliness and compatibility with other enzymatic or chemical systems have brought TAs to the attention of scientists working in the area of biocatalysis. However, to utilize TAs in a more efficient and economical way, attempts have to be made to optimize their performance. The demand for various substrate specificities, stability under non-physiological conditions and higher conversions in reversible reactions have been targeted and investigated thoroughly. A number of both protein- and process-based strategies have been developed to improve TAs and systems involving TAs. Moreover, by combination with other enzymes in cascade reactions or even in more complex systems, so called synthetic biology and systems biocatalysis, TAs can be biocatalysts with immense potential in the industrial production of ...
Biocatalysis offers an alternative to classic chemistry by using enzymes, the protein catalysts of Nature, for production of fine chemicals. Evolution has created enzymes capable of catalysis at moderate temperature of a specific reaction in the presence of a plethora of compounds in the aqueous cell environment. The focal point of biocatalysis is to utilise these traits in vitro, for creation of valuable molecules.. The ω-transaminase is an enzyme capable of producing chiral amines, compounds used to great extent in pharmaceuticals. Much effort has in recent years been invested in the research and engineering of this enzyme type since the catalysed reaction offers an advantageous alternative to classical techniques. Nevertheless, there is a need for method development, adaptation of the enzyme and increased understanding of the catalytic mechanism for feasibility as an effective biocatalyst for unnatural substrates. This thesis addresses a chosen set of obstacles as a contribution to meeting ...

Biocatalysis is an active field of research. Recent developments in bioinformatics, molecular biology, biotechnology and engineering had a huge impact on the field. Efficient cloning strategies, new expression systems for heterologous genes as well as improved purification strategies decreased costs for production of biocatalysts. Immobilization techniques increases stability under process conditions, facilitate purification of products and allow reuse of the biocatalyst. New cofactor recycling strategies and biocascades improve efficiency of processes and reduce process costs. Advances in DNA mining, protein modeling as well as efficient mutagenesis (directed evolution) and state-of-the-art screening strategies allow to design and produce enzymes for a specific application within a reasonable time span. ...

The publication covers the basics of the sphere of biocatalysis that arent handled in such aspect (or even on no account) in current biocatalysis books or biochemistry textbooks. It in fact doesnt replacement present biochemistry textbooks yet will serve an appropriate complement because it discusses biochemical basics in reference to the respective topics.. With specialise in the interdisciplinary nature of biocatalysis, the publication comprises many features of primary natural chemistry and a few of inorganic chemistry to boot, which may still make it attention-grabbing not just for biochemistry but additionally for chemistry scholars. a major subject matter being emphasised within the e-book is that utilized biocatalysis is among the major must haves for a sustainable development.. The subject matters lined levels from uncomplicated enzyme chemistry (biosynthesis, constitution, homes, interplay forces, kinetics) to an in depth description of catalytic mechanisms. It covers the basics of ...

Whereas enzymes are widely renowned for the exquisite specificity, we showed that enzymes also have low levels of catalysis for alternative reactions, an observation we described as catalytic promiscuity.. Catalytic promiscuity has been a key driver in the evolution of new enzymes, providing a head start and selective advantage for enzymes already possessing a low level of advantageous activity.. Catalytic promiscuity provides a powerful tool for addressing evolutionary and mechanistic questions. We are exploiting catalytic promiscuity across an enzyme superfamily to gain an understanding of the fundamental underpinnings of catalysis. Unlike traditional site-directed mutagenesis, experiments that are often limited to studying a single reaction catalyzed by an individual enzyme, we are using a comparative approach to ask not simply what the consequence is of removing a particular side chain, but how that removal and change in the side chain affects normal and promiscuous reactions. Because the ...

Another expression may be used (Rakels, Straathof and Heijnen, 1993): The advantage of this latter way to calculate E is that it does not involve c which may be difficult to measure accurately. As opposed to ee p and ee s which are relative quantities measured for inst in the same chromatogram, c is an absolute quantity. The most accurate way, however, is to use a computer program to fit many measured data points at several conversions to calculated curves for different E-values. The E-value is related to the difference in free energy of activation for reaction with the two enantiomers by G ‡ =−RT lnE. The ratio of the pharmacological activity of these are called the eudismic ratio (ER) and Pfeiffers rule states that the lower the effective dose of a drug the greater the difference in the pharmacological effect of the optical isomers. When two enantiometic Reactions catalysed by enzymes 21 drugs have different pharmacological effect it may be that the distomer has no effect at all and ...

This HMM describes PoyD and its homologs. These are divergent putative radical SAM enzymes, with the classical CxxxCxxC motif but with few members approaching the cutoff score of Pfam model PF04055. PoyD appears responsible for catalyzing a unidirectional L-to-D epimerization of 18 the 48 residues in the core peptide of the first characterized polytheonamide. The RiPP (ribosomally translated natural product) precursor, and peptides encoded near many other members of this family, belong to the nitrile hydratase leader peptide (NHLP) family ...

Highlights DOI: 10.1002/anie.201100070 Enzymes Expanding the Enzyme Toolbox for Biocatalysis Jacob E. Vick and Claudia Schmidt-Dannert* biocatalysis · drug discovery · enzymes · enzyme models · synthetic methods The Nomenclature Committee of the International Union of Biochemistry and Molecular Biology maintains a database of enzymes (http://www.enzyme-database.org) for the enormous task of classifying and categorizing the 5174 currently identified distinct enzymatic activities by using guidelines established by the Enzyme Commission (EC).[1] This database is filled with enzymes that have not been explored for utilization of their unique catalytic activities. An example of an enzyme that has been added to the enzyme database is the berberine bridge enzyme (BBE) [EC 1.21.3.3][2a,b] which catalyzes the conversion of the tetrahydroisoquinoline (S)-reticuline (1 a) into (S)-scoulerine (2 a; Scheme 1). BBE was first isolated from Berberis beaniana in 1985,[2c] but BBE activity was identified from ...

INTRODUCTION. The production of small or large molecules from renewable resources is central in modern chemical industry. Enzymatic catalysts are increasingly involved in processes related to the transformation / production of bio-derived materials. The evolution of the use of biological systems as producing tools can be summarised as involving the following techniques:. Extraction of natural products from plants or from natural microbial biomasses grown for the scope. Substrate modification catalysed by resting or growing cells as source of enzymatic catalysts (whole cells biotransformations). Isolated (purified ) enzymes as biocatalysts for the selective transformation of a given substrate. Modification of the metabolism of a specifi ...
