Cadmium (Cd) is a toxic heavy metal that exhibits various adverse effects in the human and animal organism. Its resemblance to essential metals such as calcium, iron, and zinc leads to an unintended uptake in cells after intake through inhalation and ingestion. In this study we investigated the toxicity and the immunomodulatory potential of Cd in… (More)
The DNA-translocator ATPase PilF of Thermus thermophilus HB27 is a hexamer built by six identical subunits. Despite the presence of a conserved zinc-binding site in every subunit, only one zinc atom per hexamer was found. Re-examination of the zinc content of PilF purified from cells grown in complex media with different lots of yeast extract revealed six… (More)
Central to the ability of Cupriavidus metallidurans to maintain its metal homoeostasis is the metal transportome, composed of uptake and efflux systems. Seven secondary metal import systems, ZupT, PitA, CorA1, CorA2, CorA3, ZntB, and HoxN, interact and are at the core of the metal uptake transportome. The 7-fold deletion mutant Δ7 (ΔzupT ΔpitA… (More)
Zinc is a central player in the metalloproteomes of prokaryotes and eukaryotes. We used a bottom-up quantitative proteomic approach to reveal the repository of the zinc pools in the proteobacterium Cupriavidus metallidurans. About 60% of the theoretical proteome of C. metallidurans was identified, quantified, and the defect in zinc allocation was compared… (More)
