Diamine oxidase of Lathyrus sativus seedlings. Purification and properties [PDF]

, 1979
Diamine oxidase (EC 1.4.3.6) was purified from 5-day-old etiolated seedlings of Lathyrus sativus by MnCl2 treatment, (NH4)2SO4 and acetone fractionations, DEAE-Sephadex chromatography followed by gel filtration on Sephadex G-200.

Histamine Intolerance: The Current State of the Art [PDF]

, 2021
Histamine intolerance, also referred to as enteral histaminosis or sensitivity to dietary histamine, is a disorder associated with an impaired ability to metabolize ingested histamine that was described at the beginning of the 21st century.

An Artificial Metal‐Free Peroxidase Designed Using a Ferritin Cage for Bioinspired Catalysis

Angewandte Chemie, EarlyView.
Designing artificial enzymes remains challenging due to the need for precise active site control. Here, we present a simple strategy to create metal‐free artificial enzymes by engineering Histidine clusters inside a ferritin cage. The resulting catalyst mimics peroxidase activity, and its stable cage structure offers new insights into supramolecular ...

New Lithium- and Diamines-Intercalated Superconductors Li$_x$(C$_2$H$_8$N$_2$)$_y$TiSe$_2$ and Li$_x$(C$_6$H$_{16}$N$_2$)$_y$TiSe$_2$ [PDF]

J. Phys. Soc. Jpn. 86, 104701 (2017), 2017
New intercalation superconductors of Li$_x$(C$_2$H$_8$N$_2$)$_y$TiSe$_2$ and Li$_x$(C$_6$H$_{16}$N$_2$)$_y$TiSe$_2$ with $T_{\rm c}$ = 4.2 K have successfully been synthesized via the co-intercalation of lithium and ethylenediamine or hexamethylenediamine into 1T-TiSe$_2$.

Probing a Complex of Cytochromecand Cardiolipin by Magnetic Circular Dichroism Spectroscopy: Implications for the Initial Events in Apoptosis [PDF]

, 2011
Oxidation of cardiolipin (CL) by its complex with cytochrome c (cyt c) plays a crucial role in triggering apoptosis. Through a combination of magnetic circular dichroism spectroscopy and potentiometric titrations, we show that both the ferric and ferrous

Is DAO in serum affected by food challenge with a histamine-rich meal?

Journal of Allergy and Clinical Immunology: Global, 2023
This case study examines the kinetics of the diamine oxidase levels after challenge with a histamine-rich meal in patients with histamine intolerance as an alternative diagnostic tool to conventional tests combined with the dietary intervention.

Polymer coated cerium oxide nanoparticles as oxidoreductase-like catalysts [PDF]

ACS Appl. Mater. Interfaces 2020, 12, 37, 42056 - 42066, 2020
Cerium oxide nanoparticles have been shown to mimic oxidoreductase enzymes by catalyzing the decomposition of organic substrates and reactive oxygen species. This mimicry can be found in superoxide radicals and hydrogen peroxides, harmful molecules produced in oxidative stress asso-ciated diseases.

Kinetics of proton pumping in cytochrome c oxidase [PDF]

J. Chem. Phys. 130, 235105 (2009), 2008
We propose a simple model of cytochrome c oxidase, including four redox centers and four protonable sites, to study the time evolution of electrostatically coupled electron and proton transfers initiated by the injection of a single electron into the enzyme.
