AI Summary
This article focuses on characterizing and tailoring the substrate profile of a specific variant of γ-glutamyltransferase. This enzyme is involved in the metabolism of glutathione, an important antioxidant in the body. By studying the substrate profile of this variant, researchers hope to understand how it differs from the wild type enzyme and how it can be manipulated to potentially enhance its activity. This research could have implications for developing new therapies for diseases involving oxidative stress.
