Arsenic mononucleotides. Separation by high-performance liquid chromatography and identification with myokinase and adenylate deaminase.
Results on the reaction mechanism of myokinase with adenosine 5'-arsenate indicate that the mixed-anhydride analogue to ADP, adenosines 5'-(arsenates phosphate), is not detected either because it is not formed in the reaction with this enzyme or because it has been rapidly hydrolyzed.
Inhibition of phosphatase and sulfatase by transition-state analogues.
It is apparent that the effectiveness of metal oxyanions as inhibitors of phosphatases and sulfatases can be selectively enhanced in the presence of other solutes.
Arsenic (V) induces a fluidization of algal cell and liposome membranes.

Vanadates as Phosphate Analogs in Biochemistry
There are two general kinds of ways in which vanadates can serve as phosphate analogs in biochemical systems. In the case of enzymes or other proteins which do not catalyse cleavage of a bond to the
GFAJ-1 Is an Arsenate-Resistant, Phosphate-Dependent Organism
It is shown that GFAJ-1 is able to grow at low phosphate concentrations, even in the presence of high concentrations of arsenate, but lacks the ability to grow in phosphorus-depleted medium, while efficiently scavenging phosphate.


Equilibrium constants of phosphoryl transfer from C-1 to C-6 of alpha-D-glucose 1-phosphate and from glucose 6-phosphate to water.
At least two enzymes having action on porphyran, the principal component of the plant, are present, and one is a sulphatase which is inhibited by citrate, and the other catalyses a reaction causing a fall in the viscosity of the polysaccharide solution.
Kinetic studies of the brain hexokinase reaction.
Factors affecting the glucose 6-phosphate inhibition of hexokinase from cerebral cortex tissue of the guinea pig.
It is concluded that ATP potentiates glucose 6-phosphate inhibition of cerebral-cortex hexokinase, whereas the ATP-Mg(2+) complex has no effect and the physiological significance of the ATP, inorganic phosphate and alpha-glycerophosphate effects is discussed.
