Understanding of Active Sites and Interconversion of Pd and PdO during CH4 Oxidation
Pd-based catalysts are widely used in the oxidation of CH4 and have a significant impact on global warming. However, understanding their active sites remains controversial, because interconversion between Pd and PdO occurs consecutively during the ...

Studies on the Active Site of Rhodanese [PDF]
Abstract The complete loss of enzymic activity on reaction with alkylating agents, aromatic nitro compounds, or aliphatic mercaptans indicates the importance of sulfhydryl groups for catalysis. Analyses during the course of inactivation with any of these reagents revealed the loss of one of the two —SH groups in the rhodanese monomer when inactivation ...

Periodic Trends in Adsorption Energies Around Single-Atom Alloy Active Sites [PDF]
Single-Atom Alloys (SAAs) are a special class of alloy surface catalysts that offer well defined, isolated active sites in a more inert metal host. The dopant sites are generally assumed to have little or no influence on the properties of the host metal, and transport of chemical reactants and products to and from the dopant sites is generally assumed ...

Potential Adiponectin Receptor Response Modifier Therapeutics
Many human diseases may benefit from adiponectin replacement therapy, but due to pharmacological disadvantages of the intact protein, druggable options focus on peptidic, and small molecule agonists of the adiponectin receptor.

Surface-Facilitated Trapping by Active Sites: From Catalysts to Viruses [PDF]
Trapping by active sites on surfaces plays important roles in various chemical and biological processes, including catalysis, enzymatic reactions, and viral entry into host cells. However, the mechanisms of these processes remain not well understood, mostly because the existing theoretical descriptions are not fully accounting for the role of the ...

Exploring the possibility of chemisorption of ethylene on graphene with and without defects [PDF]
The effect of structural defects on graphene interaction with other molecules is of high interest. In this study, the interaction of ethylene molecules with pristine graphene (PG) and defective graphenes including single (SVG) and double (DVG) vacancies,

Active Site of Cytochrome cbb3 [PDF]
Cytochrome cbb(3) is the most distant member of the heme-copper oxidase family still retaining the following major feature typical of these enzymes: reduction of molecular oxygen to water coupled to proton translocation across the membrane. The thermodynamic properties of the six redox centers, five hemes and a copper ion, in cytochrome cbb(3) from ...

Clostripain: Characterization of the active site
In view of the probability that clostripain (EC 3,4,22.8) is fundamentally different in structure from other known cysteine endopeptidases. It was of interest to examine the characteristics of the active site Z‐Pho‐Lys‐CH2S(CH3)2 irreversibly and rapidly inactivated clostripain, and leupeptin was found to be the most potent reversible inhibitor yet ...

Control of Active Sites in Flocculation: Concept of "Equivalent Active Sites"
Abstract Flocculation and dispersion of solids are strong functions of the amount and conformation of the adsorbed polymer. Regions of dispersion and flocculation of solids with particular polymer molecules may be deduced from saturation adsorption data.
