Amino acids were found in the Atlantis Massif, under the ocean floor. Is their non-biological synthesis the origin of life?
Four billion years ago the Earth cooled, cyanobacteria gave us our oxygen-rich atmosphere, and your ribosomes started synthesizing proteins!
Proteins bear a staggering collection of small chemical modifications that have large effects on their function. This research provides an elegant method to study cysteine sulfinylation, a chemical mark that has proven to be pretty elusive.
Learn about new discoveries into how plants and animals sense the world around them on a microscopic level!
New nanoparticle devices can respond to ATP levels, deliver drugs, and induce their own removal from cells. Read about the structure of these nanoparticles and how they can advance cancer therapy and diagnostics!
Just as interesting as the detail of how the antibacterial molecules works can be the new methods by which they are discovered. Today’s Chembite is about the development of antibacterial agents in the fight against an infectious bacterium.
By using a technique that allows researchers to study single molecules, scientists have gained new knowledge about how a common anti-cancer drug interacts with DNA. These findings can help explain the properties of the drug and help scientists discover novel r anti-cancer treatments with improved effectiveness.
Fluorescent proteins are incredibly useful for exploring the inside of living cells. Let’s learn about a new way to find better-performing proteins using machine learning!
Heme is central to many processes within cells, from breaking down food to energy to transporting oxygen from the air we breathe. Bound to proteins it’s extremely useful and versatile, but by itself it is highly reactive and toxic. So how does the body prevent heme from reacting before it is used in a cell?
It seems like a silly question: how can we study the function of proteins with unknown functions? The answer: with activity-based chemical probes. In this article, researchers identified several previously unexplored enzymes that may play a role in serious bacterial infections.
Title: Synergistic effects of stereochemistry and appendages on the performance diversity of a collection of synthetic compounds Authors: Stu Schreiber et al. Journal: Journal of the American Chemical Society https://pubs.acs.org/doi/10.1021/jacs.8b07319 Year: 2018 The ability to rapidly evaluate what a chemical compound does to a cell, and…
The idea that a full body scan can give comprehensive medical prognosis may be closer than we realize. Scanning mass spectrometry has been used to differentiate between healthy and cancerous skin cells. We can literally scan a person for skin cancer!
Aberrant enzyme activity drives many types of cancer and other human diseases. Traditional drugs targeting such enzymes face a variety of challenges. Here, researchers use a new small molecule “degrader” to destroy an enzyme involved in cancer.
Biological catalysts and inorganic catalysts each have their own advantages and it is sometimes difficult to choose one or the other. So why not combine them into a powerful hybrid catalyst? That’s exactly what the researchers did in this recent article from ACS Catalysis.
Successful resistance to a viral infection requires the host to deploy incredibly intricate biological tactics that somehow selectively inhibit key processes in the viral lifecycle. In this paper, researchers delve deeper into the molecular mechanisms of one of such resistance mechanisms!
Although getting the common cold is not a nice experience, it is only a relatively minor misfortune for most people. But the consqeuences of a cold can be severe. This paper describes a significant step towards a cure!
What will medicine look like 10 years from now? Well, your doctor might be shining a light on you to help target drug delivery in your body. Read more about drug delivery using molecules called photocages inside!
Microorganisms are particularly remarkable at churning out structurally challenging small molecules with interesting biological functions. In this work, an unprecedented chemical transformation in one such natural products is discovered and characterized.
A new form of DNA was found in vivo. It can be a way to regulate the DNA replication and thus prevent the replication of tumor cells.
Algal blooms aren’t the most aesthetically pleasing plant in a lake region, but did you know their emissions can impact air quality and human health?
Birds and other migratory animals use the Earth’s weak magnetic field to navigate, but what do they use as a compass? While previous research has uncovered some promising candidates, not until now have experiments identified a compass sensitive to fields as weak as Earth’s – DNA repair by photolyase.
Find out what “photochemical barcodes” are and how they might help us understand complex biological processes.
Nucleic acids are incredibly versatile molecules that can perform functions way beyond their canonical roles in biology. Here, RNA sequences are “evolved” to bind and enhance the fluorescence of a small-molecule dye, welcoming the idea of RNA for robust fluorescence imaging!
Tailoring treatment for a specific patient is the future of medicine. Let’s learn about making tiny pills that are “smart” enough to know where to dissolve in the body!
How can flavin and flavoprotein help with cancer therapy? A very nice example of biorthogonal chemistry and its potential.
