A Theoretical Study of the Benzoylformate Decarboxylase Reaction Mechanism

open access: yesFrontiers in Chemistry, 2018
Density functional theory calculations are used to investigate the detailed reaction mechanism of benzoylformate decarboxylase, a thiamin diphosphate (ThDP)-dependent enzyme that catalyzes the nonoxidative decarboxylation of benzoylformate yielding ...

Enantioselective Organocatalytic Diels-Alder Trapping of Photochemically Generated Hydroxy-o-Quinodimethanes [PDF]

open access: yes, 2016
The photoenolization/Diels-Alder strategy offers straightforward access to synthetically valuable benzannulated carbocyclic products. This historical light-triggered process has never before succumbed to efforts to develop an enantioselective catalytic ...

Selective Catalytic Oxidation of Benzyl Alcohol to Benzaldehyde by Nitrates

open access: yesFrontiers in Chemistry, 2020
In this paper, ferric nitrate was used to oxidize benzyl alcohol in a mild condition and demonstrated its better performance compared to HNO3. In the reaction, the conversion rate and product selectivity could be both as high as 95% in N2 atmosphere ...

Structural and Biochemical Analysis Reveals Catalytic Mechanism of Fucoidan Lyase from Flavobacterium sp. SA-0082

open access: yesMarine Drugs, 2022
Fucoidans represent a type of polyanionic fucose-containing sulfated polysaccharides (FCSPs) that are cleaved by fucoidan-degrading enzymes, producing low-molecular-weight fucoidans with multiple biological activities suitable for pharmacological use ...

Structural and Functional Analysis of a β2-Adrenergic Receptor Complex with GRK5. [PDF]

open access: yes, 2017
The phosphorylation of agonist-occupied G-protein-coupled receptors (GPCRs) by GPCR kinases (GRKs) functions to turn off G-protein signaling and turn on arrestin-mediated signaling.

Activation of peroxymonosulfate by CuCo2O4 nano-particles towards long-lasting removal of atrazine

open access: yesWater Reuse, 2021
The effect of peroxymonosulfate (PMS) activated by nanocrystalline CuCo2O4 (NPS) on removal of atrazine (ATZ) was studied. First, the main experimental parameters were studied, including CuCo2O4 dose, PMS dose, initial pH value, and co-existing ion.

The relationship between redox enzyme activity and electrochemical potential—cellular and mechanistic implications from protein film electrochemistry [PDF]

open access: yes, 2011
In protein film electrochemistry a redox protein of interest is studied as an electroactive film adsorbed on an electrode surface. For redox enzymes this configuration allows quantification of the relationship between catalytic activity and ...

Catalytic mechanism of F1-ATPase

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 1997
The structure of the core catalytic unit of ATP synthase, alpha 3 beta 3 gamma, has been determined by X-ray crystallography, revealing a roughly symmetrical arrangement of alternating alpha and beta subunits around a central cavity in which helical portions of gamma are found.
