Researchers Uncover Mechanism of Bacterial Enzyme in Collagen Breakdown, Paving Way for Medical Advancements
A team of international researchers, including experts from the University of Arkansas and Japanese institutions, has discovered the molecular mechanism by which bacterial collagenase breaks down collagen. This enzyme, known as ColH, engages with collagen at the atomic level to facilitate its continuous cleavage. The study, published in Nature Communications, reveals how the enzyme's unique structure allows it to degrade collagen efficiently, a process that could be harnessed for medical applications. Collagenase is used in clinical settings for isolating pancreatic islets for diabetes treatment and treating fibrotic disorders. The research highlights the enzyme's potential in enhancing chemotherapy by stripping away collagen shields around tumors, making cancer cells more vulnerable.
