Burst phase kinetics

WebIn this paper, we use the amplitude of the burst (U↔I) phase of apomyoglobin refolding to estimate the population of the kinetic intermediate (I) in various conditions. This allows us to estimate the rates of individual I→N and N→I transitions (which is the rate-limiting step of apomyoglobin folding or unfolding, respectively). WebMar 3, 2011 · Here, we propose an explicit kinetic model for this behavior, which uses classical burst phase theory as the starting point. The model is tested against calorimetric measurements of the activity of the cellobiohydrolase Cel7A from Trichoderma reesei on amorphous cellulose.
