Thermostability Measurement of an α-Glucosidase Using a Classical Activity-based Assay and a Novel Thermofluor Method
Authors:  Karin Ernits, Katrin Viigand, Triinu Visnapuu, Kristina Põšnograjeva and Tiina Alamäe, date: 06/20/2017, view: 2979, Q&A: 0
α-glucosidases (including maltases and isomaltases) are enzymes which release glucose from a set of α-glucosidic substrates. Their catalytic activity, substrate specificity and thermostability can be assayed using this trait. Thermostability of ...
