Resumen
Desarrollamos DZ-seq, un método de secuenciación de alto rendimiento para acelerar el descubrimiento de nuevos desoxiribozimas de división de ARN. Esta nueva técnica mide eficientemente la actividad catalítica e identifica sitios de escisión para miles de desoxiribozimas simultáneamente.
Área de la Ciencia:
- La bioquímica
- Biología molecular
- Enzimología
Sus antecedentes:
- Las desoxirribosimas que dividen el ARN son herramientas valiosas en la bioquímica del ARN.
- El descubrimiento de nuevos catalizadores de desoxiribozima es un desafío debido a la laboriosa selección y caracterización in vitro.
Objetivo del estudio:
- Introducir un nuevo método de secuenciación de alto rendimiento, DZ-seq, para el descubrimiento y la caracterización eficientes de los desoxiribozimas de división de ARN.
- Superar las limitaciones de los métodos tradicionales para identificar nuevos motivos catalíticos.
Principales métodos:
- Desarrolló DZ-seq, un enfoque de secuenciación de alto rendimiento.
- DZ-seq utiliza la transcripción de cola A y inversa con un primer de oligo-dT.
- El método captura el estado de escisión y las secuencias tanto de la desoxiribozima como del sustrato de ARN.
Principales resultados:
- DZ-seq mide directamente la actividad de miles de desoxiribozimas.
- El método localiza con precisión los sitios de escisión del ARN.

Ribosome Profiling
3.7K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

RNA-seq
10.5K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Maxam-Gilbert Sequencing
11.6K
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.

Ribozymes
12.7K
The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.
