Pushing and shoving: A cost factor in protein synthesis

When cells grow and proliferate, they need to produce large amounts of protein. All this protein is made by ribosomes, therefore rapid growth requires many ribosomes. Because ribosomes are expensive machines for the cell, ...

This image could lead to better antibiotics

(Phys.org) —This may look like a tangle of squiggly lines, but you're actually looking at a molecular machine called a ribosome. Its job is to translate DNA sequences into proteins, the workhorse compounds that sustain ...

Superbugs may have a soft spot, after all

The overuse of antibiotics has created strains of bacteria resistant to medication, making the diseases they cause difficult to treat, or even deadly. But now a research team at the University of Rochester has identified ...
