Vanadium biochemistry: The unknown role of vanadium-containing cells in ascidians (sea squirts)
- 56 Downloads
This article reviews several new developments in vanadium biochemistry, as elucidated from studies of ascidians. A hypothesis correlating ascidian blood cell function to anaerobiosis, via two prominent redox constituents, namely vanadium(III) and the tunichromes, a family of metal ion complexing/reducing hydroquinonoid peptides, is presented.
Key wordsVanadium ion pump tunichrome tunic ascidian respiration oxygen anaerobe
