Solute Transport Plant Plasma Membrane
The plasma membrane proton pump (H+-ATPase) energizes solute uptake by secondary transporters. Wild-type Arabidopsis plasma membrane H+-ATPase (AHA2) and truncated H+-ATPases lacking 38, 51, 61, 66, 77, 92, 96, and 104 C-terminal amino acids were produced in yeast. All AHAS species were correctly targeted to the yeast plasma membrane and, in addition, accumulated in interna1 membranes. Removal ...
متن کاملLipid rafts in the plant plasma membrane?
In order to study the molecular characteristics of an integral membrane protein, first the protein should be solubilized. Ascorbate-reducible b-type cytochromes are highly hydrophobic integral membrane proteins with six trans-membrane α-helices. A fully ascorbatereducible b-type cytochrome was easily solubilized by Triton X-100 from phase partitionpurified plasma membranes of 5-day-old etiolate...
متن کاملMethylation of aquaporins in plant plasma membrane.
A thorough analysis, using MS, of aquaporins expressed in plant root PM (plasma membrane) was performed, with the objective of revealing novel post-translational regulations. Here we show that the N-terminal tail of PIP (PM intrinsic protein) aquaporins can exhibit multiple modifications and is differentially processed between members of the PIP1 and PIP2 subclasses. Thus the initiating methion...
متن کاملCa-translocating ATPase of the plant plasma membrane.
For Ca(2+) to function as a second messenger in signal transduction, it is essential that plant cells maintain low cytoplasmic Ca(2+) levels relative to internal organelles and the apoplast. At the plasma membrane, Ca(2+) is actively transported out of the cytoplasm and current evidence supports the involvement of a primary Ca(2+)-translocating ATPase in mediating this energy-dependent process....
متن کاملPlant plasma membrane water channels conduct the signalling molecule H2O2.
H(2)O(2) is a relatively long-lived reactive oxygen species that signals between cells and organisms. H(2)O(2) signalling in plants is essential for response to stress, defence against pathogens and the regulation of programmed cell death. Although H(2)O(2) diffusion across membranes is often considered as a passive property of lipid bilayers, native membranes represent significant barriers for...
