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.

Great metalloclusters in enzymology [PDF]
Metallocluster-containing enzymes catalyze some of the most basic redox transformations in the biosphere. The reactions catalyzed by these enzymes typically involve small molecules such as N2, CO, and H2 that are used to generate both chemical building ...

A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.

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

The Stereochemical Basis of the Genetic Code and the (Mostly) Autotrophic Origin of Life
Spark-tube experiments and analysis of meteorite contents have led to the widespread notion that abiotic organic molecules were the first life components.

From Zn to Mn: the study of novel manganese-binding groups in the search for new drugs against tuberculosis. [PDF]
In most eubacteria, apicomplexans, and most plants, including the causal agents for diseases such as malaria, leprosy, and tuberculosis, the methylerythritol phosphate pathway is the route for the biosynthesis of the C(5) precursors to the essential ...

Decorin Is a Zn2+ Metalloprotein [PDF]
Decorin is ubiquitously distributed in the extracellular matrix of mammals and a member of the proteoglycan family characterized by a core protein dominated by leucine-rich repeat motifs. We show here that decorin extracted from bovine tissues under denaturing conditions or produced in recombinant "native" form by cultured mammalian cells has a high ...

Crystal structures of the NO sensor NsrR reveal how its iron-sulfur cluster modulates DNA binding
NsrR is a bacterial transcriptional regulator that acts as a nitric oxide (NO) sensor. Here, the authors present the crystal structure of NsrR, which reveals an unusual Fe-S cluster coordination and explains how NO exposure leads to the degradation of ...
