Using a powerful microscopy technique, a team led by researchers at UT Southwestern Medical Center has gained insights into how the body uses vitamin K, an essential nutrient that plays a pivotal role ...

The vitamin helps create three substances crucial to bone health: carboxylase, osteocalcin, and matrix Gla protein (MGP). Carboxylase is an enzyme required to create proteins involved in bone ...

"Acetyl-CoA carboxylase can drive the balance between storing lipids versus breaking down those lipids and feeding them into the citric acid cycle for energy," said Thaxton. "If ACC is flipped 'on ...

Vitamin K activates these proteins through a chemical reaction called carboxylation, which is mediated by an enzyme called gamma-glutamyl carboxylase (GGCX). But how GGCX facilitates this reaction has ...
