Predicting copper-, iron- and zinc-binding proteins in pathogenic species of the Paracoccidioides genus

open access: yesFrontiers in Microbiology, 2015
Approximately one-third of all proteins have been estimated to contain at least one metal cofactor, and these proteins are referred to as metalloproteins.

In Silico Simulations Reveal Molecular Mechanism of Uranyl Ion Toxicity towards DNA-Binding Domain of PARP-1 Protein

open access: yesBiomolecules, 2023
The molecular toxicity of the uranyl ion (UO22+) in living cells is primarily determined by its high affinity to both native and potential metal-binding sites that commonly occur in the structure of biomolecules.

Artificial Metalloproteins with Dinuclear Iron–Hydroxido Centers [PDF]

open access: yes, 2021
Dinuclear iron centers with a bridging hydroxido or oxido ligand form active sites within a variety of metalloproteins. A key feature of these sites is the ability of the protein to control the structures around the Fe centers, which leads to entatic ...

How Theoretical Evaluations Can Generate Guidelines for Designing/Engineering Metalloproteins with Desired Metal Affinity and Selectivity

open access: yesMolecules, 2022
Almost half of all known proteins contain metal co-factors. Crucial for the flawless performance of a metalloprotein is the selection with high fidelity of the cognate metal cation from the surrounding biological fluids.

Bioinformatic Mapping of Opine-Like Zincophore Biosynthesis in Bacteria

open access: yesmSystems, 2020
Zinc is an essential nutrient in biological systems due to its structural or catalytic requirement in proteins involved in diverse cellular processes. To meet this cellular demand, microbes must acquire sufficient zinc from their environment.

Enzyme‐Like Synthetic Cleft for Light‐Driven Water‐Oxidation Catalysis Via an Oxide Relay Pathway

open access: yesAngewandte Chemie, EarlyView.
A carboxylic acid group introduced into the second coordination sphere of a Ru(bda) water oxidation catalyst forms a defined hydrogen bond within the catalytic cleft. This interaction locks the group in place and enables an intramolecular oxide relay pathway between Ru(V)═O and the carboxylate group, providing a distinct and efficient route for O─O ...

Design of artificial metalloproteins/metalloenzymes by tuning noncovalent interactions [PDF]

open access: green, 2017
Noncovalent weak interactions [hydrophobic interaction and hydrogen (H)-bond] play crucial roles in controlling the functions of biomolecules, and thus have been used to design artificial metalloproteins/metalloenzymes during the past few decades.

Oxygen‐Tolerant Photo‐Induced Miniaturized Accelerated Atom Transfer Radical Polymerization (OPTIMA‐ATRP) for High‐Throughput Synthesis of Polymer Bioconjugates

open access: yesAngewandte Chemie, EarlyView.
Oxygen‐tolerant photo‐induced miniaturized accelerated atom transfer radical polymerization (OPTIMA‐ATRP) in water was developed for the polymerization of hydrophilic (meth)acrylate monomers under ambient or sub‐ambient (4°C) temperature and atmospheric conditions, without prior degassing, in less than 10 min, at an ultra‐small scale (< 50 µL) in ...

The Stereochemical Basis of the Genetic Code and the (Mostly) Autotrophic Origin of Life

open access: yesLife, 2014
Spark-tube experiments and analysis of meteorite contents have led to the widespread notion that abiotic organic molecules were the first life components.
