The role in the substrate specificity and catalysis of residues forming the substrate aglycone-binding site of a beta-glycosidase
(BLACKWELL PUBLISHING, 2008)
The relative contributions to the specificity and catalysis of aglycone, of residues E190, E194, K201 and M453 that form the aglycone-binding site of a beta-glycosidase from Spodoptera frugiperda (EC 3.2.1.21), were ...
Theoretical and experimental study of the catalytic cathodic stripping square-wave voltammetry of chromium species
(Springer, 2016-12)
The electrocatalytic mechanism of Cr(III) reduction in the presence of diethylenetriaminepentaacetic acid (DTPA) and nitrate ions is studied theoretically and experimentally by using stripping square-wave voltammetry (SWV). ...
