BIORESOURCE TECHNOLOGY 2021; 326:124665. [PMID: 33540211 DOI: 10.1016/j.biortech.2021.124665] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 12/30/2020] [Accepted: 12/31/2020] [Indexed: 06/12/2023]
Abstract
Leucine dehydrogenase (LDH) is widely used in the preparation of L-2-aminobutyric acid (L-2-ABA), however its wide application is limited by 2-ketobutyric acid (2-OBA) inhibition. Firstly, a novel high-throughput screening method of LDH was established, specific enzyme activity and 2-OBA tolerance of Lys72Ala mutant were 33.3% higher than those of the wild type. Subsequently, we constructed a single cell comprised of ivlA, EsldhK72A, fdh and optimized expression through fine-tuning RBS intensity, so that the yield of E. coli BL21/pET28a-R3ivlA-EsldhK72A-fdh was 2.6 times higher than that of the original strain. As a result, 150 g L-threonine was transformed to 121 g L-2-ABA in 5 L fermenter with 95% molar conversion rate, and a productivity of 5.04 g·L-1·h-1, which is the highest productivity of L-2-ABA currently reported by single-cell biotransformation. In summary, our research provided a green synthesis for L-2-ABA, which has potential for industrial production of drug precursors.

Abstract
In recent decades, enzymes have been the target of considerable research, development,
and innovation. This paper presents an up-to-date overview of the technological application of lipases
in the pharmaceutical industry. Lipases have been used in a variety of ways in the pharmaceutical
industry, both for obtaining bioactive molecules to overcome limitations in the formulation of medicines
and in drug design. This is possible from alternative technologies, such as immobilization and
the use of non-aqueous solvents that allow the use of lipases in commercial-scale processes. In addition,
other technologies have provided the emergence of differentiated and more specific lipases in
order to meet the perspectives of industrial processes. The research indicates that the following years
should be promising for the application of lipase in the industrial biocatalysis and in drug design.

Recent achievements in developing the biocatalytic toolbox for chiral amine synthesis. Curr Opin Chem Biol 2014; 19:180-92.

Abstract
Novel enzyme activities and chemoenzymatic reaction concepts have considerably expanded the biocatalytic toolbox for chiral amine synthesis. Creating new activities or extending the scope of existing enzymes by protein engineering is a common trend in biocatalysis and in chiral amine synthesis specifically. For instance, an amine dehydrogenase that allows for the direct asymmetric amination of ketones with ammonia was created by mutagenesis of an l-amino acid dehydrogenase. Another trend in chiral amine chemistry is the development of strategies allowing for the synthesis of secondary amines. For example the smart choice of substrates for amine transaminases provided access to secondary amines by chemoenzymatic reactions. Furthermore novel biocatalysts for the synthesis of secondary amines such as imine reductases and Pictet-Spenglerases have been identified and applied. Recent examples showed that the biocatalytic amine synthesis is emerging from simple model reactions towards industrial scale preparation of pharmaceutical relevant substances, for instance, as shown in the synthesis of a Janus kinase 2 inhibitor using an amine transaminase. A comparison of important process parameters such as turnover number and space-time yield demonstrates that biocatalytic strategies for asymmetric reductive amination are maturing and can already compete with established chemical methods.
