Figure 3From: Intrinsic thermodynamics of ethoxzolamide inhibitor binding to human carbonic anhydrase XIIIObserved enthalpies of EZA (a) and TFMSA (b) binding to hCA XIII in TRIS chloride (■) and sodium phosphate (◯) buffer, 25°C, are shown as a function of pH. Datapoints represent observed enthalpies obtained by ITC, while the curves are fitted according to Eq. (4).Back to article page
