Summary
This study introduces a novel enzymatic method for synthesizing nucleoside-5'-triphosphates (NTPs) and their analogs. This efficient one-pot process offers a sustainable alternative to chemical synthesis for pharmaceutical and molecular biology applications.
Area of Science:
- Biochemistry
- Synthetic Biology
- Enzymology
Background:
- Nucleoside-5'-triphosphates (NTPs) are essential for DNA and have critical roles in pharmaceuticals and molecular biology.
- Current chemical synthesis of NTPs, especially modified analogs, is often inefficient and time-consuming.
- There is a need for improved, scalable methods for NTP production.
Purpose of the Study:
- To develop a simple, efficient, and generalizable enzymatic method for synthesizing NTPs from nucleosides.
- To demonstrate the modularity and broad applicability of the one-pot enzymatic approach.
- To improve conversion rates using a (deoxy)ATP recycling system.
Main Methods:
- A one-pot enzymatic cascade utilizing nucleoside kinases, nucleoside monophosphate (NMP) kinases, and nucleoside diphosphate (NDP) kinases.
- Combination of enzymes with diverse substrate specificities for producing various NTP derivatives.
- Implementation of a (deoxy)ATP recycling system to enhance reaction efficiency.
Main Results:
- The enzymatic method successfully synthesized natural and modified NTPs with high conversions (up to >99%).
- Adenosine and cytidine triphosphate derivatives were produced with 4-26% conversion initially, significantly improved by the recycling system.
- Sugar- and base-modified NTPs were synthesized with conversions ranging from 27% to >99%.
Conclusions:
- The developed enzymatic method provides an efficient, sustainable, and generalizable one-pot process for NTP synthesis.
- This approach is suitable for producing a wide array of natural and modified NTPs, overcoming limitations of chemical synthesis.
- The method holds significant potential for applications in molecular biology and pharmaceutical development.

6.7K
Biological macromolecules are organic compounds, predominantly composed of carbon atoms. The carbon atoms are covalently bonded with hydrogen, oxygen, nitrogen, and other minor elements. There are four major biological macromolecule classes: carbohydrates, lipids, proteins, and nucleic acids.
Most macromolecules are composed of single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers.

01:48ATP Synthase: Mechanism
16.2K
In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased...

Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...

01:22Amplifying Signals via Enzymatic Cascade
16.4K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

14.5K
ATP synthase or ATPase is among the most conserved proteins found in bacteria, mammals, and plants. This enzyme can catalyze a forward reaction in response to the electrochemical gradient, producing ATP from ADP and inorganic phosphate. ATP synthase can also work in a reverse direction by hydrolyzing ATP and generating an electrochemical gradient. Different forms of ATP synthases have evolved special features to meet the specific demands of the cell. Based on their specific feature, ATP...

12.2K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
