Discovery of a new vanadium accumulator, the fan wormPseudopotamilla occelata

The Chemistry and Biochemistry of Vanadium and the Biological Activities Exerted by Vanadium Compounds

“…Most of the vanadium is believed to be in oxidation state III and a high level of sulfate is found in the vanadium-containing cells. 520,521 Although the vanadocytes are quite different between ascidians and this fan worm, it is presumably significant that the storage locale and form seem to be the same in these animals. 520,521 The role of vanadium in these animals is not known.…”

Vanadium and proteins: Uptake, transport, structure, activity and function

“…Amounts of vanadium existing in marine organisms, with particular emphasis on hyperaccumulation of V in polychaetes, was recently revised by Fattorini and Regoli [65] and previously by Ishii [60]. Particularly elevated concentrations of vanadium were measured in branchial crowns of Perkinsiana littoralis.…”

“…The accumulation of V is also found in other marine organisms namely in polychaetes, with special emphasis on tube-dwelling fan worms of the Sabellidae family [60] [61] [62] [63] [64]. Vanadium contents are in the range of 320 to 1350 g/g of dry weight of the whole body.…”

N,N′‐Ethylenebis(pyridoxylideneiminato) and N,N′‐Ethylenebis(pyridoxylaminato): Synthesis, Characterization, Potentiometric, Spectroscopic, and DFT Studies of Their Vanadium(IV) and Vanadium(V) Complexes

“…[3] Three types of vanadiumcontaining enzymes are known: vanadium nitrogenases, [4] vanadium-dependent haloperoxidases, [5] and vanadium-containing nitrate reductases. [6,7] Among other biological effects, vanadium×s insulin-like action [8] and anticancer activity [9] have stimulated a considerable amount of research.…”
