For over 350 years, quinine and other extracts from the cinchona tree (Cinchona spp.) were the only effective medicines ...

By reconstructing ancient nitrogen-processing enzymes, scientists are uncovering new clues about how early life survived on a very different Earth.

Researchers have found that peroxiredoxins, a family of antioxidant enzymes central to how cells manage oxidative stress, can ...

A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, ...

Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

RIKEN researchers have demonstrated a method that can detect tiny amounts of biomarkers in liquid samples and can distinguish between highly similar biomarkers. This promises to boost the versatility ...

Researchers have found evidence of nuclear metabolic enzymes for the first time, contributing to our understanding of cancer ...

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic ...

Most people believe they eat enough fiber, but research shows at least 9 out of 10 don’t. That means 90% of Americans are falling short on a key part of a diet that protects against a range of ...

Way back when, digestive issues were a thing many people kept under wraps. Now, it’s become increasingly clear that a lot of people suffer from digestive problems like bloating, constipation, diarrhea ...

Enzymes are proteins that facilitate biochemical reactions by acting as a catalyst, and thus, their expression and activity have a strong influence on the reactions taking place within cells. As ...
