Researchers at New York University and the University of Chicago have developed artificial, fully synthetic cell-like structures that autonomously ingest, process, and push out material, recreating an ...

Integral outer membrane receptors for iron chelates and vitamin B 12 carry out specific ligand transport against a concentration gradient. Energy for active transport is obtained from the ...

Acidification of intracellular compartments by the vacuolar-type H+-ATPases (VHA) is known to energize ion and metabolite transport, though cellular processes influenced by this activity are poorly ...

For decades it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers have now elucidated the transport path ...
