The dication lies across a crystallographic inversion center.
2
Ready generation of radical cations was supported by cyclic voltammetry measurements, revealing stepwise formation of radical cation and dication species in solution.
3
Spectroscopic studies indicated that these radical cations and dications have good stability.
4
In substitution reactions at the phosphorus atom the triflyloxy moiety serves as a leaving group and enables the synthesis of rare examples of pseudo-halophosphonium dications.

1
Upon Zn binding the two lobes close tightly around the divalentcation.
2
Interestingly, the majority of hop-regulated enzymes are described as manganese or divalentcation dependent.
3
Brush border membranes were isolated from rat jejunum by a divalentcation precipitation method.
4
The cytoplasmic domain contains several histidines and cysteines, perhaps indicative of divalentcation binding sites.
5
Brush border membranes were isolated from rat renal cortex by a divalentcation precipitation method.
6
This suggests that the extracellular divalentcation requirement varies for different lighting paradigms that promote shedding.
7
The guanine nucleotide selectivity sequence and the divalentcation requirements were also similar for both responses.
8
The C2A domain binds to phospholipid membranes and other accessory proteins in a divalentcation-dependent fashion.
9
The activity-dependent inactivation depends on divalentcation influx.
10
This reduction in driving force for calcium currents eliminated divalentcation influx and abolished the activity-dependent inactivation.
11
The divalentcation is essential for both reactions and may be directly involved in stabilizing the transition state.
12
Magnesium is an abundant divalentcation in plant cells and plays a critical role in many physiological processes.
13
Aggregation occurred at millimolar concentrations of divalentcation and was inhibited and reversed by the addition of EDTA.
14
Aggregation depends on the addition of a divalentcation and varies inversely with the ionic radius of the cation.
15
The enzyme exhibits a strict preference for Mg(+2) as a divalentcation and CTP as the nucleotide.
16
The Ki value for ADP inhibition of F1-catalyzed ATP hydrolysis with magnesium as divalentcation present was found to be temperature-independent.
