BioMetals

BioMetals is a well established, international, multidisciplinary journal solely devoted to the rapid publication of articles and reviews in this unique field. BioMetals features the fundamental advances in both basic and applied research which involve the role of metal ions in chemistry, biology, biochemistry, and medicine. BioMetals topic areas include: structures of new metal binding ligands, their interaction with proteins and membrane receptors as well as the biosynthesis gene regulation and metabolic pathways of intra- and extracellular metal binding compounds Homeostasis of essential metals the protection against metal toxicity by metalloregulatory proteins and the prevention of reactive oxygen species caused by certain metal ions transport proteins, transcription factors and cellular sensors that play a pivotal role in the uptake, efflux and storage of metal ions like iron, zinc, copper and other metal ions BioMetals provides a forum for new research and clinical results on the structure and function of metal ions, metal chelates, siderophores, metal-containing proteins and biominerals in all kinds of biosystems. Thus, metal ions in bacterial, fungal, plant, animal and other eukaryotic cells are all considered. Biosorption, bioremediation and environmental pollution studies may be submitted, provided that they give an insight into novel molecular mechanisms or important developments in practical applications.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
