membrane channel

A transmembrane protein complex which allows water (aquaporin) and inorganic ions (ion channels) to passively diffuse across the membrane bilayer down an electrochemical gradient.

This difference suggests that disruption of tolC, which encodes TolC outer membrane channel protein, an integral part of AcrAB-TolC channel, may affect the structural integrity of the outer membrane of S.
This new research shows how specific P450 genes can engender resistance across insecticides with entirely different modes of action: DDT and pyrethroids target a voltage-gated sodium channel (a nerve cell membrane channel), whereas carbamates and organophosphates target the neurotransmitter Acetylcholinesterase, encoded by the gene ACE-1.
In this preparation, DOSs are obtained by gentle mechanical trituration of dark-adapted retinas with no alteration of membrane channel proteins due to proteolytic enzymes.
The bulk concentration [C.sub.b] and solvent transports Jv vary along the membrane channel. The computation of the mass transfer coefficient [k.sub.c] is as follows [19]:
US and European biological and medical researchers offer a reference and textbook on the connexin family of membrane channel proteins.
By genetically engineering the flies to express a particular membrane channel in their neurons, the researchers were able to install the equivalent of a remote control into the insects' brains.
The researchers used those discoveries to predict how the three-molecule structure of the pump's third part, the outer membrane channel known as CusC, interacts with the CusBA complex.
The membrane's purple color comes from a bacteriorhodopsin component called retinal, which is strongly bound to an amino acid inside the membrane channel. Unbound retinal in solution is pale yellow.
