Abstract:
... The vast diversity and membrane-bound nature of plant P450s makes it challenging to study the structural characteristics of this class of enzymes especially with respect to accurate intermolecular enzyme-substrate interactions. To address this problem we here apply a modified hybrid structure strategy for homology modeling of plant P450s. This allows for structural elucidation based on conserved m ...

Abstract:
... Oxidative stress and autophagy dysfunction are critical factors in the pathogenesis of atherosclerosis. Adenosine 5′ monophosphate-activated protein kinase (AMPK) plays an important role in inhibiting oxidative stress and promoting autophagy. Catalpol, an iridoid glucoside extracted from the root of Rehmanniae glutinosa L, was reported to produce a potent antioxidant effect. However, the mechanism ...

However, the wide application of tannin is restricted by its low reactivity. Therefore, the goal of this study was to enhance the reactivity of larch tannin by depolymerization and determine optimal reaction conditions. The structures of larch tann ...
