Functional expression of the Enterococcus hirae NaH-antiporter in Escherichia coli.
We recently described the cloning of napA, the putative structural gene for the NaH-antiporter of Enterococcus hirae (Waser, M., Bienz-Hess, D., Davies, K., and Solioz, M. (1992) J. Biol. Chem. 267, 5396-5400). To analyze the gene product of napA, we expressed it in Escherichia coli. When placed under the control of a T7 promoter, napA could be transcribed and labeled specifically with [35S]met...
متن کاملCloning and disruption of a putative NaH-antiporter gene of Enterococcus hirae.
When growing in a sodium-rich environment, wild-type Enterococcus hirae extrudes sodium by two mechanisms, ATP-driven sodium extrusion, and NaH-antiport. Mutant 7683 is unable to grow on sodium-rich media. This is due to two mutations, one inactivating ATP-driven sodium transport and a second rendering NaH-antiport inoperative. 7683 was transformed by electroporation with a gene bank, derived f...
متن کاملAltered Na+ and Li+ homeostasis in Saccharomyces cerevisiae cells expressing the bacterial cation antiporter NhaA.
The bacterial Na+ (Li+)/H+ antiporter NhaA has been expressed in the yeast Saccharomyces cerevisiae. NhaA was present in both the plasma membrane and internal membranes, and it conferred lithium but not sodium tolerance. In cells containing the yeast Ena1-4 (Na+, Li+) extrusion ATPase, the extra lithium tolerance conferred by NhaA was dependent on a functional vacuolar H+ ATPase and correlated ...

15 صفحه اولthe significance of conjunction as a cohesive device in teaching writing
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
