Heavy metal regulation of plasma membrane H+-ATPase gene expression in halophyte Aeluropus littoralis
The present study was conducted to find the effect of three heavy metals, Ag, Hg and Pb on the expression level of a gene encoding plasma membrane H+-ATPase in Aeluropus littoralis. The experiment was laid out in a completely random design with three replications. The expression of the main gene was normalized to the expression of the housekeeping gene actin. Two 259 and 187 bp fragments were a...
متن کاملBiogenesis and function of the yeast plasma-membrane H(+)-ATPase.
One of the most abundant proteins in the yeast plasma membrane is the P-type H(+)-ATPase that pumps protons out of the cell, supplying the driving force for a wide array of H(+)-dependent cotransporters. The ATPase is a 100 kDa polypeptide, anchored in the lipid bilayer by 10 transmembrane alpha-helices. It is structurally and functionally related to the P-type Na(+),K(+)-, H(+),K(+)- and Ca(2+...
متن کاملUp-regulation of plasma membrane H+-ATPase under salt stress may enable Aeluropus littoralis to cope with stress
Plasma membrane H+-ATPase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. To study the effect of NaCl on the expression pattern of a gene encoding the plasma membrane H+-ATPase, an experiment was carried out in a completely random design with three replications. A pair of specific primers was designed based on the sequence o...
متن کاملStructure, mechanism, and regulation of the Neurospora plasma membrane H+-ATPase.
Proton pumps in the plasma membrane of plants and yeasts maintain the intracellular pH and membrane potential. To gain insight into the molecular mechanisms of proton pumping, we built an atomic homology model of the proton pump based on the 2.6 angstrom x-ray structure of the related Ca2+ pump from rabbit sarcoplasmic reticulum. The model, when fitted to an 8 angstrom map of the Neurospora pro...
متن کاملStructure of a plasma membrane H+-ATPase gene from the plant Arabidopsis thaliana.
Physiological and biochemical studies have suggested that the plant plasma membrane H+-ATPase controls many important aspects of plant physiology, including growth, development, nutrient transport, and stomata movements. We have started the genetic analysis of this enzyme by isolating both genomic and cDNA clones of an H+-ATPase gene from Arabidopsis thaliana. The cloned gene is interrupted by ...
