Vascular thiol isomerases [PDF]

Blood, 2016
AbstractThiol isomerases are multifunctional enzymes that influence protein structure via their oxidoreductase, isomerase, and chaperone activities. These enzymes localize at high concentrations in the endoplasmic reticulum of all eukaryotic cells where they serve an essential function in folding nascent proteins.

Multistage, Self‐Sensing Artificial Muscles With Coordination From Liquid Crystal Elastomer‐Graphene Composite Fibers

Advanced Functional Materials, EarlyView.
Inspired by skeletal muscles’ precision and endurance, CoilLCE integrates a self‐sensing liquid crystal elastomer/graphene artificial muscle with an embedded Joule‐heating copper coil, enabling closed‐loop multistage actuation with programmable intermediate states (strain accuracy of 2%), and antagonistic coordination (32% total strain). These features

Synthesis of low molecular weight thiols in response to Cd exposure in Thlaspi caerulescens

, 2006
In this study, we investigated the accumulation of phytochelatins (PCs) and other low molecular weight (LMW) thiols in response to Cd exposure in two contrasting ecotypes differing in Cd accumulation.

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams

Advanced Functional Materials, EarlyView.
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

The Thiol Groups of Fumarase

Journal of Biological Chemistry, 1967
Several reagents have been employed to determine the role of the thiol groups in fumarase. The nature of the reaction of these reagents indicates that the thiol groups are not associated with active site structures but are buried in a hydrophobic environment in the interior of the enzyme. Several observations are in accord with this view.
