Introduction: In the vast palette of nature’s creations, melanin stands out as a pigment of remarkable complexity and importance. Found in varying concentrations across living organisms, melanin plays diverse roles, from determining skin color to protecting against harmful UV radiation. This article aims to delve into the fascinating world of melanin, exploring its structure, functions,…
Malonic acid is an important intermediate, and its derivatives have important applications in the fields of medicine, agriculture, chemical industry, and food processing. It can be expressed in Escherichia coli through β- The alanine pathway achieves biosynthesis, with a yield of 3.6 g/L. Fu Wenxuan and others followed the path of phosphoenolpyruvate/pyruvate → oxaloacetic acid…
Highlights Metabolic flux provides quantitative insights into carbon, energy, and electron flow. Flux Balance Analysis (FBA) evaluates the ability of metabolic network models. 13C Metabolic flux analysis (13C MFA) is used to estimate flux with high precision. The new method of 13C-MFA can measure flux in complex, non-standard biological systems. The predictive kinetic model of…
Proteins are one of the most important molecules in living organisms, with an extremely wide range of functions and roles. Traditionally, researchers can use cell expression systems to prepare the required proteins and conduct in-depth research on them. However, due to factors such as cell growth, maintenance, and contamination, the cell expression system faces some…
Overview In November of this year, the Medicines and Health Products Regulatory Authority (MHRA) in the UK approved a CRISPR/Cas9 gene editing therapy for sickle cell disease, which caused quite a sensation at the time. It should be noted that this was the world’s first approved CRISPR therapy. Although CRISPR technology has been highly sought…
Prime Editing is another technology developed by Professor David R. Liu’s team at Harvard University for precise gene editing, following Base Editing. The development of PE perfectly solves the problem of being able to effectively repair only four gene mutations (i.e. C → T, G → A, A → G, and T → C) in…
When it comes to molecular cloning, almost every friend who has done plasmid construction knows about Gibson Assembly, and this method is really popular! I remember when I first entered the laboratory, my senior brothers and sisters taught me that the method used to construct plasmids was Gibson Assembly. At that time, the entire laboratory…
Glucose metabolism refers to all processes involved in breaking down or re forming glucose. Glycolysis is the process of breaking down glucose into molecules such as pyruvate and ATP. It occurs within the cytoplasm and does not require oxygen. This makes glucose an anaerobic process. In the absence of oxygen, the pyruvate molecules formed during…
MRNA (messenger RNA) is an important molecular biology messenger that can carry genetic information within cells, converting genetic information in DNA into instructions for protein synthesis. In recent years, mRNA technology has received increasing attention in the medical field, especially in vaccine development and gene therapy. With the rapid development of genomics and proteomics, people’s…
In the realm of protein research, few names resonate as deeply as that of David Baker. His significant work has effectively sculpted our understanding of proteins, their complex structures, and their multifaceted functions. This blog aims to delve into Baker’s remarkable contributions, providing an in-depth exploration of his work on protein structure prediction, protein design,…
