The heat released during catalytic turnover enhances the diffusion of an enzyme
(Macmillan, 2015)
Recent studies have shown that the diffusivity of enzymes increases
in a substrate-dependent manner during catalysis1,2. Although this
observation has been reported and characterized for several different
systems3–10, ...
Characterization of gelatinase produced by Antarctic Mrakia sp.
(Wiley-VCH Verlag, 2019)
In the present study, 20 psychrotolerant yeast species isolated from the soils of King George Island in the sub-Antarctic region were evaluated for the production of extracellular gelatinase, an enzyme with high potential ...
Activity of pectic enzymes involved in the ripening process of lulo (solanum quitoense lam.)
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2011)
In the ripening process of the lulo (Solanum quitoense Lam.) physicochemical changes are produced by pectics enzymes as Polygalacturonase (PG), Pectinesterase (PE) and Pectateliase (PL) that acting on pectics substrates ...
One-step combined focused epPCR and saturation mutagenesis for thermostability evolution of a new cold-active xylanase
(Elsevier, 2017)
tEnzymes active at low temperature are of great interest for industrial bioprocesses due to their highefficiency at a low energy cost. One of the particularities of naturally evolved cold-active enzymes istheir increased ...
BETA-GLUCOSIDASE FROM PENICILLIUM-PURPUROGENUM - PURIFICATION AND PROPERTIES
(PORTLAND PRESS, 1992-04)
Beta-glucosidade was purified from the culture supernatant of penicillium purpurogenum. The purified enzyme was homogeneous on both nondenaturing and sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis. The ...
Phenotypic flexibility in the intestinal enzymes of the African clawed frog Xenopus laevis
(ELSEVIER SCIENCE INC, 2005-01)
The intestinal plasticity of digestive enzymes of amphibian species is poorly known. The goal of this study was to characterize digestive enzyme profiles along the small intestine of adult frogs, Xenopus laevis, in response ...
Changes of enzyme activity in lipid signaling pathways related to substrate reordering
(BIOPHYSICAL SOCIETY, 2005-08)
The static fluid mosaic model of biological membranes has been progressively complemented by a dynamic membrane model that includes phospholipid reordering in domains that are proposed to extend from nanometers to microns. ...
Tuning of conformational dynamics through evolution-based design modulates the catalytic adaptability of an extremophilic kinase
(American Chemical Society, 2020)
Conformational flexibility plays a critical role in enzyme function and is a key aspect in transitions from an open to a closed state induced by substrate binding and product release. Psychrophilic enzymes display a high ...
