Subsequent steps include iron being transferred to surface lipoproteins, then to transport proteins which carry the iron into the cell.
32.
This protein is homologous to FecA, FepA and FhuA, outer membrane iron transport proteins that presumably function by similar mechanisms.
33.
Transport proteins are integral transmembrane proteins; that is they exist permanently within and span the membrane across which they transport substances.
34.
It has been speculated that the Mg 2 + ion will initially interact with any transport protein through its hydration shell.
35.
A membrane transport protein ( or simply " transporter " ) is a membrane protein that acts as such a carrier.
36.
However, there is a known transport mechanism to move PEP from the mitochondria to the cytosol, using specific membrane transport proteins.
37.
First, the affected gene in most cases is that for a transport protein ( StAR ) rather than a steroidogenic enzyme.
38.
The twin-arginine translocation pathway is an important pathway involved in virulence, which transports proteins through the cell membrane of the bacteria.
39.
This asymmetric phospholipid distribution among the bilayer is the result of the function of several energy-dependent and energy-independent phospholipid transport proteins.
40.
The endoplasmic reticulum also helps transport proteins, fats, and other materials to specific sites within the cell or to the cell surface.
