This study presents a protocol for synthesizing modified nucleoside triphosphates (dN*TPs) for enzymatic DNA synthesis. This method offers an alternative to traditional oligonucleotide synthesis, enabling applications like aptamer selection.
Area of Science:
- Biochemistry
- Molecular Biology
- Synthetic Chemistry
Background:
- Chemical modification of nucleic acids is crucial for various biotechnological applications.
- Traditional solid-phase synthesis of oligonucleotides has limitations and drawbacks.
- Enzymatic polymerization using modified nucleoside triphosphates (dN*TPs) offers an alternative approach.
Purpose of the Study:
- To describe a protocol for synthesizing modified nucleoside triphosphates (dN*TPs).
- To evaluate the substrate acceptance of these dN*TPs by polymerases.
- To demonstrate their utility in applications such as aptamer selection.
Main Methods:
- Development of a protocol for synthesizing modified nucleoside triphosphates (dN*TPs).
- Evaluation of polymerase substrate acceptance for synthesized dN*TPs.
- Exemplification of the protocol using a sugar-constrained nucleoside analog (7',5'-bc-TTP).
Main Results:
- Successful synthesis protocol for modified dN*TPs established.
- Demonstrated polymerase acceptance of synthesized dN*TPs.
- Validated utility in selection experiments for aptamer identification.
Conclusions:
- The described protocol provides a viable method for producing modified dN*TPs.
- Enzymatic polymerization with these modified dN*TPs is effective for various applications.
- This approach expands the toolkit for nucleic acid modification and selection.

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
