A functional assay will be designed to further characterise VAChT activities by reconstituting the transporter and ATPase
into a proteoliposome.
enzyme activity investigation
The researchers observed three principal modes of coordinated hydrolysis, featuring hydrolytic events in two oppositely positioned ATPases
, in two adjacent ATPases
, and in one ATPase
at a time.
The role of cation activated ATPase
in transmitter release from the rat iris.
 These two cations are in balance with each other, because of Na+ - K+ - ATPase
pump, which in turn maintains permeability of lens membrane.
Several researchers reported that in IDA, the activity of red cell membrane-bound [Na.sup.+][K.sup.+]ATPase is altered and due to this altered ATPase
activity, serum sodium, and potassium levels are affected.
Figure 2(a) shows that the [Na.sup.+]/[K.sup.+]-ATPase activity in the control increased for 12 h, whereas ATPase
activity increased from 0 to 8 h and then decreased from 8 to 12 h before increasing again from 12 to 24 h when treated with BPCE.
Androgens have been suggested to increase the expression of the Na-K ATPase
and explain the male to female prevalence to have been reported to be from 20 to 44: 1 [5,9], although the prevalence of hyperthyroidism of male to female is 1: 10.
The activation of [Na.sup.+]-[K.sup.+] ATPase
leads to a shift of potassium ions intracellularly, resulting in hypokalaemia and hyperpolarisation of muscle cell membranes .
Myosin globular head is responsible for the ATPase
ATP1AL1 gene is transcriptionally competent and probably encodes the related ion transport ATPase

[F.sub.1] can be solubilized and the isolated [F.sub.1] functions only as ATPase
