Cation Transport in Yeast
1. The distribution of azide added to suspensions of bakers' yeast was studied under various conditions. The recovery of azide was estimated in the volume of water into which low concentrations of electrolytes can readily diffuse (anion space). Considerable azide disappeared from this anion space. 2. The incomplete recovery of azide in the anion space is due to its uptake by the cells. This upt...
متن کاملCation Transport in Escherichia coli
K influx and net K flux have been measured in suspensions of chloramphenicol-arrested Escherichia coli. The rate of K exchange in the steady state was independent of the K concentration of the medium over a 200-fold range. Under a number of experimental conditions the rate of exchange may be considerably increased or decreased without changing the cellular K content. These results show that und...
متن کاملLETM1 in mitochondrial cation transport
LETM1 (leucine zipperEF handcontaining transmembrane 1) encodes a highly conserved eukaryotic protein of the mitochondrial inner membrane which is essential to control mitochondrial volume homeostasis. Indeed, LETM1 RNA interference causes severe mitochondrial changes that include massive matrix swelling, loss of cristae structure and network fragmentation in S. cerevisiae (Nowikovsky et al., 2...
متن کاملCation Transport in Escherichia coli
The present study is concerned with the measurement of the unidirectional K flux in E, coli. Methods are described by means of which a fairly dense suspension of cells may be maintained in a well defined steady-state with respect to the intracellular K concentration and the pH of the medium. The kinetics of K 4~ exchange under these conditions are consistent with the presence of a single intrac...
متن کاملA rice tonoplastic calcium exchanger, OsCCX2 mediates Ca2+/cation transport in yeast
In plant cell, cations gradient in cellular compartments is maintained by synergistic action of various exchangers, pumps and channels. The Arabidopsis exchanger family members (AtCCX3 and AtCCX5) were previously studied and belong to CaCA (calcium cation exchangers) superfamily while none of the rice CCXs has been functionally characterized for their cation transport activities till date. Rice...
