Vanadate
PubChem Notes:
Vanadates Oxyvanadium ions in various states of oxidation. They act primarily as ion transport inhibitors due to their inhibition of Na(+)-, K(+)-, and Ca(+)-ATPase transport systems. They also have insulin-like action, positive inotropic action on cardiac ventricular muscle, and other metabolic effects.
Vanadate - definition from Biology-Online.org
[VO4(3) powerful inhibitor of many, but not all enzymes that cleave the terminal phosphate bond of aTP. The vanadate ion is believed to act as an analogue of the transition state of the cleavage reaction. dynein is very sensitive to inhibition by vanadate, whereas kinesin is relatively insensitive. Similarly tyrosine kinases are sensitive to vanadate, but threonine/serine protein kinases are insensitive.
