Obstruction of Water Uptake in cut Chrysanthemum Stems after Dry Storage: Role of Wound-induced Increase in Enzyme Activities and Air Emboli [PDF]

, 2009
Hydraulic conductance of cut chrysanthemum stems was lowered by the aspiration of air as well as by a wound-induced plant response. By measuring the hydraulic conductance of stem segments in which air could be introduced into and/or removed from the ...

Enzymatically Active Ultrathin Pepsin Membranes

Angewandte Chemie, 2015
AbstractEnzymatically active proteins enable efficient and specific cleavage reactions of peptide bonds. Covalent coupling of the enzymes permits immobilization, which in turn reduces autolysis‐induced deactivation. Ultrathin pepsin membranes were prepared by facile interfacial polycondensation of pepsin and trimesoyl chloride.

On the Enzymatic Activation of NADH [PDF]

Journal of Biological Chemistry, 2001
Atomic (1 A) resolution x-ray structures of horse liver alcohol dehydrogenase in complex with NADH revealed the formation of an adduct in the active site between a metal-bound water and NADH. Furthermore, a pronounced distortion of the pyridine ring of NADH was observed.

Enzymatic Activity of Xyloglucan Xylosyltransferase 5 [PDF]

Plant Physiology, 2016
Xyloglucan, the most abundant hemicellulosic component of the primary cell wall of flowering plants, is composed of a β-(1,4)-glucan backbone decorated with d-xylosyl residues. Three xyloglucan xylosyltransferases (XXTs) participate in xyloglucan biosynthesis in Arabidopsis (Arabidopsis thaliana).

Three-Dimensional Printable Enzymatically Active Plastics [PDF]

ACS Applied Polymer Materials, 2021
Here, we describe a facile route to the synthesis of enzymatically active highly fabricable plastics, where the enzyme is an intrinsic component of the material. This is facilitated by the formation of an electrostatically stabilized enzyme-polymer surfactant nanoconstruct, which, after lyophilization and melting, affords stable macromolecular ...
