Imposing function down a (cupin)-barrel: secondary structure and metal stereochemistry in the αKG-dependent oxygenases

The Fe(II)/αketoglutarate (αKG) dependent oxygenases catalyze a diverse range of reactions significant in biological processes such as antibiotic biosynthesis, lipid metabolism, oxygen sensing, and DNA and RNA repair.

Iron-responsive bacterial small RNAs: variations on a theme

Variations in bacterial iron-responsive small RNA function are intimately linked to the lifestyle of the bacteria that encode them.

Campylobacter jejuni ferric–enterobactin receptor CfrA is TonB3 dependent and mediates iron acquisition from structurally different catechol siderophores

C. jejuni exploits a large variety of catechol siderophores for growth and most depend on either the CfrA transporter or the TonB3 energy transduction system for their use.

Effect of aluminium and copper on biofilm development of Pseudomonas pseudoalcaligenes KF707 and P. fluorescens as a function of different media compositions

The toxicity of a metal towards bacteria is dependent upon a three-way interaction between the metal, the bacterium and the physicochemical properties of the environment/media.

The BaeSR regulon is involved in defense against zinc toxicity in E. coli

Intracellular zinc concentration fluxes demonstrate that proteins in the BaeSR regulon (MdtABC, MdtD and Spy) are important for zinc detoxification.

Exposure of Bacillus subtilis to mercury induces accumulation of shorter tRNACys species

The effects of mercury on tRNA metabolism are investigated using Northern blotting with wild type, single and double mutants of RNases in Bacillus subtilis and CVAAS.

Aerobic uranium immobilization by Rhodanobacter A2-61 through formation of intracellular uranium–phosphate complexes

Rhodanobacter A2-61 can actively grow aerobically in the presence of U, and can efficiently remove U(VI) and inorganic phosphate from the environment, accumulating them inside the cell in complexes, that corresponds to effective metal immobilization.

A copper hyperaccumulation phenotype correlates with pathogenesis in Cryptococcus neoformans

Cellular metal analysis reveals that the virulence of Cryptococcus neoformans depends upon its ability to acquire unusually high copper concentrations during infection.

Streptococcus pneumoniae requires iron for its viability and expresses two membrane proteins that bind haemoglobin and haem

Streptococcus pneumoniae, a human pathogen bacterium, can support its growth using haemoglobin (Hb) and haem as sole iron sources, but not when holo-transferrin is supplied.

Co(II)-detection does not follow Kco(II) gradient: channelling in Co(II)-sensing

Cobalt sensing CoaR has the weakest affinity for cobalt among a set of metal sensors from the same cell, indicating a kinetic contribution to metal-selectivity.

Selenite and tellurite form mixed seleno- and tellurotrisulfides with CstR from Staphylococcus aureus

The sulfite sensor from Staphylococcus aureus reacts with the related chalcogen oxyanion selenite to form a novel intersubunit selenotrisulfide linkage.

The Porphyromonas gingivalis HmuY haemophore binds gallium(III), zinc(II), cobalt(III), manganese(III), nickel(II), and copper(II) protoporphyrin IX but in a manner different to iron(III) protoporphyrin IX

Porphyromonas gingivalis HmuY binds non-iron metalloporphyrins but in a manner different to haem which might be exploited to reduce the virulence of this bacterium.

The molybdoproteome of Starkeya novella – insights into the diversity and functions of molybdenum containing proteins in response to changing growth conditions

The metabolic versatility of the soil bacterium Starkeya novella is underpinned by a variety of novel mononuclear Mo enzymes, many of which show growth mode dependent expression.

Cold-adapted arsenite oxidase from a psychrotolerant Polaromonas species

The cold-adapted arsenite oxidase is more active and less thermostable than its mesophilic homologues, which can be explained by its increased flexibility and a reduction in the hydrophobicity of the core.
