"With an average concentration of 35 nM, vanadium (essentially present in the form of ion pairs Na+H2VO4-) is the second- to-most abundant transition metal in sea water, outclassed only by molybdenum (present as molybdate MoO42, ca. 100 nM). Vanadate-dependent haloperoxidases (VHPOs) can be present in marine brown, green and red algae, in (symbiotic) marine cyanobacteria, in Streptomyces bacteria, and in terrestrial fungi and lichen. Since the discovery of the first representative of these haloperoxidases, the bromoperoxidase VBrPO of the brown alga Ascophyllum nodosum , also known as knobbed wreck or pig weed, a plethora of macroalgae has been reported to have available VHPOs.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
