Synth Syst Biotechnol 2024; 9:99-107. [PMID: 38288444 PMCID: PMC10823089 DOI: 10.1016/j.synbio.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 12/10/2023] [Accepted: 01/05/2024] [Indexed: 01/31/2024] Open
Abstract
Creatine is a naturally occurring derivative of an amino acid commonly utilized in functional foods and pharmaceuticals. Nevertheless, the current industrial synthesis of creatine relies on chemical processes, which may hinder its utilization in certain applications. Therefore, a biological approach was devised that employs whole-cell biocatalysis in the bacterium Corynebacterium glutamicum, which is considered safe for use in food production, to produce safe-for-consumption creatine. The objective of this study was to identify a guanidinoacetate N-methyltransferase (GAMT) with superior catalytic activity for creatine production. Through employing whole-cell biocatalysis, a gamt gene from Mus caroli (Mcgamt) was cloned and expressed in C. glutamicum ATCC 13032, resulting in a creatine titer of 3.37 g/L. Additionally, the study employed a promoter screening strategy that utilized nine native strong promoters in C. glutamicum to enhance the expression level of GAMT. The highest titer was achieved using the P1676 promoter, reaching 4.14 g/L. The conditions of whole-cell biocatalysis were further optimized, resulting in a creatine titer of 5.42 g/L. This is the first report of successful secretory creatine expression in C. glutamicum, which provides a safer and eco-friendly approach for the industrial production of creatine.

[PMID: 36941436 DOI: 10.1007/s00253-023-12482-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 02/10/2023] [Accepted: 03/12/2023] [Indexed: 03/23/2023]
Abstract
Seleno-methylselenocysteine (SeMCys) is an effective component for selenium supplementation with anti-carcinogenic potential and can ameliorate neuropathology and cognitive deficits. In this study, we aimed to engineer Bacillus subtilis 168 for the microbial production of SeMCys. First, the accumulation of intracellular selenocysteine (SeCys) as the precursor of SeMCys was enhanced through overexpression of serine O-acetyltransferase, which was desensitized against feedback inhibition by cysteine. Next, the S-adenosylmethionine (SAM) synthetic pathway was optimized to improve methyl donor availability through expression of S-adenosylmethionine synthetase. Further, SeMCys was successfully produced through expression of the selenocysteine methyltransferase in SeCys and SAM-producing strain. The increased expression level of selenocysteine methyltransferase benefited the SeMCys production. Finally, all the heterologous genes were integrated into the genome of B. subtilis, and the strain produced SeMCys at a titer of 18.4 μg/L in fed-batch culture. This is the first report on the metabolic engineering of B. subtilis for microbial production of SeMCys and provides a good starting point for future pathway engineering to achieve the industrial-grade production of SeMCys. KEY POINTS: • Expression of the feedback-insensitive serine O-acetyltransferase provided B. subtilis the ability of accumulating SeCys. • SAM production was enhanced through expressing S-adenosylmethionine synthetase in B. subtilis. • Expression of selenocysteine methyltransferase in SeCys and SAM-accumulating strain facilitated SeMCys production.

High-Throughput Screening and Directed Evolution of Methionine Adenosyltransferase from Escherichia coli. Appl Biochem Biotechnol 2023:10.1007/s12010-023-04314-2. [PMID: 36652094 DOI: 10.1007/s12010-023-04314-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/06/2023] [Indexed: 01/19/2023]
Abstract
S-adenosyl-L-methionine (SAM) is the active form of methionine, which participates in various metabolic reactions and plays a vital role. It is mainly used as a precursor by three key metabolic pathways: trans-methylation, trans-sulfuration, and trans-aminopropylation. Methionine adenosyltransferase (MAT) is the only enzyme to produce SAM from methionine and ATP. However, there is no efficient and accurate method for high-throughput detection of SAM, which is the major obstacles of directed evolution campaigns for MAT. Herein, we established a colorimetric method for directed evolution of MAT based on detecting SAM by using glycine oxidase and glycine/sarcosine N-methyltransferase enzyme. Screening of MAT libraries revealed variant I303V/Q22R with 2.13-fold improved activity towards SAM in comparison to the wild type. Molecular dynamic simulation indicates that the loops more flexible and more conducive to SAM release.

Abstract
Ferulic acid (p-hydroxy-3-methoxycinnamic acid, FA) is a natural active substance present in plant cell walls, with antioxidant, anticancer, antithrombotic and other properties; it is widely used in medicine, food, and cosmetics. Production of FA by eco-friendly bioprocess is of great potential. In this study, FA was biosynthesized by metabolically engineered Escherichia coli. As the first step, the genes tal (encoding tyrosine ammonia-lyase, RsTAL) from Rhodobacter sphaeroides, sam5 (encoding p-coumarate 3-hydroxylase, SeSAM5) from Saccharothrix espanaensis and comt (encoding Caffeic acid O-methytransferase, TaCM) from Triticum aestivum were cloned in an operon on the pET plasmid backbone, E. coli strain containing this construction was proved to produce FA from L-tyrosine successfully, and confirmed the function of TaCM as caffeic acid O-methytransferase. Fermentation result revealed JM109(DE3) as a more suitable host cell for FA production than BL21(DE3). After that the genes expression strength of FA pathway were optimized by tuning of promoter strength (T7 promoter or T5 promoter) and copy number (pBR322 or p15A), and the combination p15a-T5 works best. To further improve FA production, E. coli native pntAB, encoding pyridine nucleotide transhydrogenase, was selected from five NADPH regeneration genes to supplement redox cofactor NADPH for converting p-coumaric acid into caffeic acid in FA biosynthesis process. Sequentially, to further convert caffeic acid into FA, a non-native methionine kinase (MetK from Streptomyces spectabilis) was also overexpressed. Based on the flask fermentation data which show that the engineered E. coli strain produced 212 mg/L of FA with 11.8 mg/L caffeic acid residue, it could be concluded that it is the highest yield of FA achieved by E. coli K-12 strains reported to the best of our knowledge.

Abstract
Three genes, gnd, pgl, and fbp, relevant to the pentose phosphate pathway (PPP) were overexpressed in Corynebacterium glutamicum IWJ001, leading to increase of l-isoleucine production. The transcriptional levels of gnd, pgl, and fbp significantly increased in IWJ001/pDXW-8-gnd-fbp-pgl. Compared with the control strain IWJ001/pDXW-8, intracellular NADPH/NADP+ ratios in IWJ001/pDXW-8-gnd and IWJ001/pDXW-8-gnd-fbp cells grown for 36 H increased threefold and fourfold, respectively, indicating that overexpression of gnd and fbp redirected the carbon flux to PPP. Intracellular NADPH/NADP+ ratio in IWJ001/pDXW-8-gnd-fbp-pgl grown for 36 H was similar to IWJ001/pDXW-8, suggesting that the NADPH produced by PPP could be quickly consumed for l-isoleucine production. 10.9 and 28.96 g/L of l-isoleucine was produced in IWJ001/pDXW-8-gnd-fbp-pgl in shake flask cultivation and fed-batch fermentation, respectively. In addition, IWJ001/pDXW-8-gnd-fbp-pgl grew fast, its dry cell weight reached 49 g/L after 48 H, whereas the start strain IWJ001/pDXW-8 reached only 40 g/L. After 96 H fermentation, l-isoleucine yield on glucose in IWJ001/pDXW-8-gnd-fbp-pgl reached 0.138 g/g. The results demonstrate that carbon flux redirection to PPP is an efficient approach to enhance l-isoleucine production in C. glutamicum.
