Chemistry 2024; 30:e202401193. [PMID: 38652483 DOI: 10.1002/chem.202401193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 04/22/2024] [Accepted: 04/23/2024] [Indexed: 04/25/2024]
Abstract
Here we report the efficient synthetic access to 13C/15N-labelled pseudouridine phosphoramidites, which were incorporated into a binary H/ACA box guide RNA/product complex comprising 77 nucleotides (nts) in total and into a 75 nt E. coli tRNAGly. The stable isotope (SI) labelled pseudouridines were produced via a highly efficient chemo-enzymatic synthesis. 13C/15N labelled uracils were produced via chemical synthesis and enzymatically converted to pseudouridine 5'-monophosphate (ΨMP) by using YeiN, a Ψ-5'-monophosphate C-glycosidase. Removal of the 5'-phosphate group yielded the desired pseudouridine nucleoside (Ψ), which was transformed into a phosphoramidite building suitable for RNA solid phase synthesis. A Ψ -building block carrying both a 13C and a 15N label was incorporated into a product RNA and the complex formation with a 63 nt H/ACA box RNA could be observed via NMR. Furthermore, the SI labelled pseudouridine building block was used to determine imino proton bulk water exchange rates of a 75 nt E. coli tRNAGly CCmnm5U, identifying the TΨC-loop 5-methyluridine as a modifier of the exchange rates. The efficient synthetic access to SI-labelled Ψ building blocks will allow the solution and solid-state NMR spectroscopic studies of Ψ containing RNAs and will facilitate the mass spectrometric analysis of Ψ-modified nucleic acids.

Abstract
Multi-enzyme cascade reactions for the synthesis of complex products have gained importance in recent decades. Their advantages compared to single biotransformations include the possibility to synthesize complex molecules without purification of reaction intermediates, easier handling of unstable intermediates, and dealing with unfavorable thermodynamics by coupled equilibria. In this study, a four-enzyme cascade consisting of ScADK, AjPPK2, and SmPPK2 for ATP synthesis from adenosine coupled to the cyclic GMP-AMP synthase (cGAS) catalyzing cyclic GMP-AMP (2'3'-cGAMP) formation was successfully developed. The 2'3'-cGAMP synthesis rates were comparable to the maximal reaction rate achieved in single-step reactions. An iterative optimization of substrate, cofactor, and enzyme concentrations led to an overall yield of 0.08 mole 2'3'-cGAMP per mole adenosine, which is comparable to chemical synthesis. The established enzyme cascade enabled the synthesis of 2'3'-cGAMP from GTP and inexpensive adenosine as well as polyphosphate in a biocatalytic one-pot reaction, demonstrating the performance capabilities of multi-enzyme cascades for the synthesis of pharmaceutically relevant products.

Abstract
Covering: up to the beginning of 2020Enzymes depending on cofactors are essential in many biosynthetic pathways of natural products. They are often involved in key steps: catalytic conversions that are difficult to achieve purely with synthetic organic chemistry. Hence, cofactor-dependent enzymes have great potential for biocatalysis, on the condition that a corresponding cofactor regeneration system is available. For some cofactors, these regeneration systems require multiple steps; such complex enzyme cascades/multi-enzyme systems are (still) challenging for in vitro biocatalysis. Further, artificial cofactor analogues have been synthesised that are more stable, show an altered reaction range, or act as inhibitors. The development of bio-orthogonal systems that can be used for the production of modified natural products in vivo is an ongoing challenge. In light of the recent progress in this field, this review aims to provide an overview of general strategies involving enzyme cofactors, cofactor analogues, and regeneration systems; highlighting the current possibilities for application of enzymes using some of the most common cofactors.

Abstract
An ATP regeneration system is advantageous for industrial processes that are coupled with ATP-dependent enzymes. For ATP regeneration from AMP, a few methods have been reported; however, these methods employ multiple enzymes. To establish an ATP regeneration system using a single enzyme, we focused on class III polyphosphate kinase 2 (class III PPK2) that can synthesize ATP from AMP and polyphosphate. We constructed an ATP regeneration system from AMP using Deipr_1912, a class III PPK2 from Deinococcus proteolyticus NBRC 101906T, coupled with aminoacyl proline (Xaa-Pro) synthesis catalyzed by the adenylation domain of tyrocidine synthetase A (TycA-A). Using this system, 0.87 mM of l-Trp-l-Pro was successfully synthesized from AMP after 72 h. Farther, addition of inorganic pyrophosphatase from Escherichia coli to the coupling reaction increased the reaction rate by 14-fold to yield 6.2 mM l-Trp-l-Pro. When the coupling reaction was applied to whole-cell reactions in E. coli BL21(DE3) pepQ-putA-, ATP was successfully regenerated from AMP by Deipr_1912, and 6.7 mM of l-Trp-l-Pro was produced after 24 h with the supplementation of 10 mM AMP. In addition, by altering the substrate amino acid of TycA-A, not only l-Trp-l-Pro, but also various other l-Xaa-l-Pro (Xaa = Val, Leu, Met, or Tyr) were produced using the whole-cell reaction incorporating ATP regeneration. Therefore, a production method for Xaa-Pro employing the adenylation domain of a nonribosomal peptide synthetase was established by introducing an ATP regeneration system that utilizes class III PPK2 with pyrophosphatase.

Abstract
The similar L-arginine molecule aggregation has been found in L-arginine (LA) and L-arginine phosphate monohydrate (LAP) aqueous solutions. The special fluorescence emission at 380 nm of LA aggregates in LAP solution has been found, compared with the emission of LA solution at 415 nm, which has an obvious blue shift. By comparing the fluorescence spectra of several solutions for L-arginine and L-lysine salts, the interaction between phosphate and guanidine in LAP solution was considered to be the cause of its special fluorescence emission. Meanwhile, when LAP molecule formed in solution, the fluorescence emission wavelength and the UV absorption intensity at 296 nm of L-arginine solutions have mutated. Therefore, the group interaction involved by guanidine has changed the fluorescence properties of L-arginine aggregates in LAP solution, indicating that the specific interaction between phosphate and guanidine exists in LAP molecule.

Abstract
Adenosine-5'-triphosphate-dependent enzyme catalysed reactions are widespread in nature. Consequently, the enzymes involved have an intrinsic potential for use in syntheses of high value products. Although regeneration systems for ATP starting from adenosine-5'-diphosphate are available, certain limitations exist for both in vitro and in vivo applications requiring ATP regeneration from adenosine-5'-monophosphate, or adenosine. Following a short overview of the chemical and thermodynamic background, this Minireview focuses on emerging enzymes and methodologies for ATP regeneration. A large range of as yet unexploited reactions will be accessible with new, powerful, multistep ATP regeneration systems that use cheap phosphate donors and provide high longevity, compatibility, and robustness under process conditions. Their potential might go far beyond the direct use of ATP in enzymatic reactions; enzyme discovery, and engineering, as well as immobilisation strategies, will help to realise such systems.
