Hierarchically-structured metalloprotein composite coatings biofabricated from co-existing condensed liquid phases [PDF]

open access: yesNature Communications, 2020
The mussel byssus cuticle is a wear-resistant and extensible metalloprotein composite. Here, the authors probed the cuticle nanostructure and composition before, during and after fabrication revealing a crucial role of metal-binding proteins that self ...

Recent advances and future challenges in predictive modeling of metalloproteins by artificial intelligence [PDF]

open access: yesMolecules and Cells
: Metal coordination is essential for structural/catalytic functions of metalloproteins that mediate a wide range of biological processes in living organisms. Advances in bioinformatics have significantly enhanced our understanding of metal-binding sites

Improving Data Representation of Metalloproteins in the Protein Data Bank [PDF]

open access: yesStructural Dynamics
The Protein Data Bank (PDB) was established in 1971 as the first open-access digital data resource in biology, initially comprising just seven X- ray crystal structures of proteins.

Changing paradigms for the micronutrient zinc, a known protein cofactor, as a signal relaying also cellular redox state [PDF]

open access: yesQuantitative Plant Biology
The micronutrient zinc (Zn) is often poorly available but toxic when present in excess, so a tightly controlled Zn homoeostasis network operates in all organisms. This review summarizes our present understanding of plant Zn homoeostasis.

Methanogenesis marker 16 metalloprotein is the primary coenzyme M synthase in Methanosarcina acetivorans. [PDF]

open access: yesPLoS Genetics
2-mercaptoethanesulfonate (Coenzyme M, CoM) is an organic sulfur-containing cofactor used for hydrocarbon metabolism in archaea and bacteria. In archaea, CoM serves as an alkyl group carrier for enzymes belonging to the alkyl-CoM reductase family ...

Investigation of the Ferredoxin’s Influence on the Anaerobic and Aerobic, Enzymatic H2 Production

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Ferredoxins are metalloproteins that deliver electrons to several redox partners, including [FeFe] hydrogenases that are potentially a component of biological H2 production technologies.

Copper Cytotoxicity: Cellular Casualties of Noncognate Coordination Chemistry

open access: yesmBio, 2022
Copper (Cu) is an essential micronutrient for cells, but in excess it is cytotoxic. How Cu is cytotoxic is the subject of recent work by L. Zuily, N.

Structure of the membrane-bound formate hydrogenlyase complex from Escherichia coli

open access: yesNature Communications, 2022
New cryo-EM structures of the formate hydrogenlyase complex from the model bacterium E. coli clarify how electrons and protons move through the complex and are combined to make H2 gas.

Towards the spatial resolution of metalloprotein charge states by detailed modeling of XFEL crystallographic diffraction. [PDF]

open access: yes, 2020
Oxidation states of individual metal atoms within a metalloprotein can be assigned by examining X-ray absorption edges, which shift to higher energy for progressively more positive valence numbers.

Toxic Metal Species and ‘Endogenous’ Metalloproteins at the Blood–Organ Interface: Analytical and Bioinorganic Aspects

open access: yesMolecules, 2021
Globally, human exposure to environmental pollutants causes an estimated 9 million deaths per year and it could also be implicated in the etiology of diseases that do not appear to have a genetic origin.
