Nature catalysis | Production of natural products through Escherichia coli metabolic engineering using electronic channels

Research background: The biosynthesis of natural products usually requires the binding of eukaryotic cytochrome P450 (P450) to P450 reductase, which is physically close and undergoes electron transfer reactions. Research question: Unfortunately, the functional expression of eukaryotic p450 in bacteria is often still difficult. Research content and results: 1) The author of this article artificially approached…

Nature: Breakthroughs in DNA synthesis technology, and artificial genomes are just around the corner?

DNA is a fundamental component of life and a core material in synthetic biology. Synthetic biology is an emerging interdisciplinary field that utilizes engineering principles and techniques to design and construct biological systems with specific functions. The application prospects of synthetic biology are very broad, involving multiple fields such as medicine, agriculture, energy, environment, and…

Research progress in DNA synthesis, assembly, and error correction techniques

DNA design and synthesis are key common underlying technologies that drive the development of life sciences and related fields. Conventional genetic manipulation techniques can only make limited modifications to existing DNA sequences, while DNA synthesis techniques can “write” life information from scratch, enhancing our ability to understand, predict, and manipulate living organisms from another perspective….

Glutathione, an antioxidant “artifact”

In daily life, we often see sliced apples being oxidized in the air, and the flesh gradually turns from white to yellow brown. However, our human body also experiences this kind of oxidation. The human body continuously produces free radicals due to continuous contact with the outside world, including respiration (oxidation reaction), metabolism, external pollution,…

The Path to Fame of Escherichia coli

Theodor Escherich, an outstanding physician and scientist of the 19th century, was one of the earliest scientists to explore microorganisms. He founded the field of intestinal pathology and associated his name with the name Escherichia coli, which was discovered and named in 1885. From then on, the “E.coli clan” was endowed with the fate of…

New Achievements in Cell Genomics Construction of Artificial Synthetic Yeast, Revealing Two Different Pathways of Non ploidy Phenotypic Restoration

  In 2011, countries such as the United States, China, the United Kingdom, Singapore, and Australia launched the “Sc2.0 Project” to redesign and synthesize all 16 chromosomes of brewing yeast. This was the first attempt by humans to design and synthesize the genome of eukaryotes from scratch. On November 8, 2023, the latest research findings…

The first CRISPR therapy has been approved, and which new round of gene editing is about to enter the clinical trial stage?

Less than a month after the world’s first approval of CRISPR-Cas9 genome editing therapy, this therapy received a second approval – this time from the United States, due to its strict regulation and lucrative healthcare market. The UK regulatory agency approved this therapy on November 16th, which inactivates a gene as a means of treating…

《Cell》breaks the world record for yeast! The Miracle of Artificial Life

Despite containing only 7.5 artificial chromosomes, highly edited strains still survive and replicate. Biologists have developed a yeast whose genome contains over 50% of artificially synthesized DNA. Standard brewing yeast (Saccharomyces cerevisiae) stores its genetic blueprint on 16 chromosomes. In the new strain, 6.5 of these chromosomes were edited and synthesized in the laboratory, while…
