A functional assay will be designed to further characterise VAChT activities by reconstituting the transporter and
ATPase into a proteoliposome.
Ca2+-activated
ATPase 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.
[6] 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 [1].
Myosin globular head is responsible for the
ATPase activity [16].
ATP1AL1 gene is transcriptionally competent and probably encodes the related ion transport
ATPase," FEBS Letters, vol.
[F.sub.1] can be solubilized and the isolated [F.sub.1] functions only as
ATPase.
