Combined DFT and MD Simulation Protocol to Characterize Self-Healing Properties in Disulfide-Containing Materials: Polyurethanes and Polymethacrylates as Case Studies

Frontiers in Materials, 2022
The introduction of dynamic bonds in polymeric materials facilitates the emergence of new functionalities, such as self-healing capacity. Understanding the role of the molecular structure in the efficiency of the self-healing process is fundamental to ...

Multistep, sequential control of the trafficking and function of the multiple sulfatase deficiency gene product, SUMF1 by PDI, ERGIC-53 and ERp44. [PDF]

, 2008
Sulfatase modifying factor 1 (SUMF1) encodes for the formylglicine generating enzyme, which activates sulfatases by modifying a key cysteine residue within their catalytic domains. SUMF1 is mutated in patients affected by multiple sulfatase deficiency, a

Quantification of thiols and disulfides [PDF]

Biochimica et Biophysica Acta (BBA) - General Subjects, 2014
Disulfide bond formation is a key posttranslational modification, with implications for structure, function and stability of numerous proteins. While disulfide bond formation is a necessary and essential process for many proteins, it is deleterious and disruptive for others.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Interrelations Between the Enthalpies of Formation of the Sulfur-Containing Amino Acids L-Cystine, L-Cysteine and L-Methionine

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science
L-Cystine, L-cysteine, and L-methionine are among the twenty-two L-α-amino acids from which all proteins are composed. With their unique sulphur atoms, Lcystine, L-cysteine, and L-methionine have been particularly problematic with regard to both ...

Vitamin D and thiol-disulfide homeostasis levels in postmenopausal women with overactive bladder syndrome [PDF]

Journal of Medical Biochemistry, 2020
Background: This study aimed to find a relationship between vitamin D concentration and thiol-disulfide homeostasis in the pathophysiology of overactive bladder (OAB) syndrome in postmenopausal women. Methods: A total of 76 postmenopausal women, referred

Interleukin-2 signalling is modulated by a labile disulfide bond in the CD132 chain of its receptor [PDF]

Open Biology, 2012
Certain disulfide bonds present in leucocyte membrane proteins are labile and can be reduced in inflammation. This can cause structural changes that result in downstream functional effects, for example, in integrin activation.
