Current Opinion in Chemical Biology

The Current Opinion journals were developed out of the recognition that it is increasingly difficult for specialists to keep up to date with the expanding volume of information published in their subject. In Current Opinion in Chemical Biology, we help the reader by providing in a systematic manner:
1. The views of experts on current advances in chemical biology in a clear and readable form.
2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.

Division of the subject into sections:
The subject of chemical biology is divided into themed sections which are reviewed regularly to keep them relevant. For 2015 they are:

  • Omics
  • Bioinorganic chemistry
  • Biocatalysis and Biotransformation
  • Next Generation Therapeutics
  • Molecular Imaging
  • Synthetic Biology
  • Synthetic Biomolecules
  • Energy
  • Mechanistic Biology

Selection of topics to be reviewed:
Section Editors, who are major authorities in the field, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasised. Section Editors commission reviews from authorities on each topic that they have selected.

Reviews:
Authors write short review articles in which they present recent developments in their subject, emphasising the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.

Editorial Overview:
Section Editors write a short overview at the beginning of the section to introduce the reviews and to draw the reader's attention to any particularly interesting developments.
This successful format has made Current Opinion in Chemical Biology one of the most highly regarded and highly cited review journals in the field.

Ethics in Publishing: General Statement
The Editor(s) and Publisher of this Journal believe that there are fundamental principles underlying scholarly or professional publishing. While this may not amount to a formal 'code of conduct', these fundamental principles with respect to the authors' paper are that the paper should: i) be the authors' own original work, which has not been previously published elsewhere, ii) reflect the authors' own research and analysis and do so in a truthful and complete manner, iii) properly credit the meaningful contributions of co-authors and co-researchers, iv) not be submitted to more than one journal for consideration, and v) be appropriately placed in the context of prior and existing research. Of equal importance are ethical guidelines dealing with research methods and research funding, including issues dealing with informed consent, research subject privacy rights, conflicts of interest, and sources of funding. While it may not be possible to draft a 'code' that applies adequately to all instances and circumstances, we believe it useful to outline our expectations of authors and procedures that the Journal will employ in the event of questions concerning author conduct. With respect to conflicts of interest, the Publisher now requires authors to declare any conflicts of interest that relate to papers accepted for publication in this Journal. A conflict of interest may exist when an author or the author's institution has a financial or other relationship with other people or organizations that may inappropriately influence the author's work. A conflict can be actual or potential and full disclosure to the Journal is the safest course. All submissions to the Journal must include disclosure of all relationships that could be viewed as presenting a potential conflict of interest. The Journal may use such information as a basis for editorial decisions and may publish such disclosures if they are believed to be important to readers in judging the manuscript. A decision may be made by the Journal not to publish on the basis of the declared conflict.

Metal-associated amyloid-β species in Alzheimer's disease

Highly concentrated metals such as Cu, Zn, and Fe are found in amyloid-β (A. β) plaques within the brain of Alzheimer's disease (AD). In vitro and in vivo studies have suggested that metal binding to A. β could facilitate A. β aggregation and generate reactive oxygen species (ROS), which could contribute to the neuropathogenesis of AD. The connection between metal-A. β interaction/reactivity and AD development, however, has not been clearly revealed owing to the complexity of the disease. In…

Recent insights into iron import by bacteria

Bacteria are confronted with a low availability of iron owing to its insolubility in the Fe3+ form or its being bound to host proteins. The bacteria cope with the iron deficiency by using host heme or siderophores synthesized by themselves or other microbes. In contrast to most other nutrients, iron compounds are tightly bound to proteins at the cell surfaces, from which they are further translocated by highly specific proteins across the cell wall of gram-positive bacteria and the outer…
