The NOX Family of Proteins Is Also Present in Bacteria

mBio, 2017
Transmembrane NADPH oxidase (NOX) enzymes have been so far only characterized in eukaryotes. In most of these organisms, they reduce molecular oxygen to superoxide and, depending on the presence of additional domains, are called NOX or dual oxidases ...

Development of novel anilinoquinazoline-based carboxylic acids as non-classical carbonic anhydrase IX and XII inhibitors

Journal of Enzyme Inhibition and Medicinal Chemistry, 2023
As part of our ongoing endeavour to identify novel inhibitors of cancer-associated CA isoforms IX and XII as possible anticancer candidates, here we describe the design and synthesis of small library of 2-aryl-quinazolin-4-yl aminobenzoic acid ...

Oxygen Activation by Mononuclear Mn, Co, and Ni Centers in Biology and Synthetic Complexes [PDF]

, 2017
The active sites of metalloenzymes that catalyze O2-dependent reactions generally contain iron or copper ions. However, several enzymes are capable of activating O2 at manganese or nickel centers instead, and a handful of dioxygenases exhibit activity ...

Rapid and Precise Determination of Zero-Field Splittings by Terahertz Time-Domain Electron Paramagnetic Resonance Spectroscopy

, 2017
Zero-field splitting (ZFS) parameters are fundamentally tied to the geometries of metal ion complexes. Despite their critical importance for understanding the magnetism and spectroscopy of metal complexes, they are not routinely available through general

Biochemical characterization of the native α-carbonic anhydrase purified from the mantle of the Mediterranean mussel, Mytilus galloprovincialis

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017
A α-carbonic anhydrase (CA, EC 4.2.1.1) has been purified and characterized biochemically from the mollusk Mytilus galloprovincialis. As in most mollusks, this α-CA is involved in the biomineralization processes leading to the precipitation of calcium ...

New isoxazolidinyl-based N-alkylethanolamines as new activators of human brain carbonic anhydrases

Journal of Enzyme Inhibition and Medicinal Chemistry, 2023
Carbonic anhydrases (CAs) are widespread metalloenzymes which catalyse the reversible hydration of carbon dioxide (CO2) to bicarbonate (HCO3−) and a proton, relevant in many physiological processes. In the last few years, the involvement of CA activation

Ciprofloxacin enhances the stimulation of matrix metalloproteinase 3 expression by interleukin-1beta in human tendon-derived cells [PDF]

, 2002
To determine whether the fluoroquinolone antibiotic ciprofloxacin, which can cause tendon pain and rupture in a proportion of treated patients, affects the expression of matrix metalloproteinases (MMPs) in human tendon-derived cells in culture.

Atomically Precise Clusterzymes: A Programmable Optoelectronic Platform for Neuroscience

Advanced Science, EarlyView.
Atomically precise clusterzymes, engineered via atomic and ligand design, serve as programmable platforms for neuroscience applications. They demonstrate tailored biocatalysis for neuroinflammation, tunable optical properties for deep‐tissue bioimaging and 3D visualization, and enhanced charge transfer for brain–computer interfaces.
