Copenhagen remains the benchmark as cities around the world try to figure out how to take the bicycle seriously as a mode of transport again, and enable this 19th-century invention to solve 21st-century urban challenges.
There is comprehensive evidence of the positive health effects of physical activity, and transport authorities can enable this by developing infrastructure for cycling and walking.
These proteins enable the transport of essential nutrients and ions, plus the excretion of end products of metabolism and cell-environment communication [ 23].
These proteins enable the transport of essential nutrients and ions, in addition to the excretion of end products of metabolism and cell-environment communication [ 38].
Milk ducts of the mammary gland course to the surface of the nipple and enable the transport of breast milk during lactation [ 3, 4].
For instance, SNAREs must be transported to a given organelle membrane so that they can subsequently be sorted into transport vesicles and tubules leaving that membrane since this enables these transport vesicles/tubules to fuse, ultimately, with their desired target membrane, into which the correct cognate SNAREs must have already been placed.
This in turn enables the transport vesicle to proceed for fusion with the plasma membrane (Chen et al. 2011a, b).
Examples include nitrogenase, which enables the fixation of nitrogen, and hemoglobin, which enables the transport of oxygen.
In this study, however, a novel streptavidin fusion protein TAT-SA [ 10] was examined, which enables the transport of biotinylated cargoes into cells.
These FG repeats can bind and then release the transport factors at unusually high speeds, which enables the transport factors to move quickly through the nuclear pore complex.
