Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E. coli ...

MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria ...

Despite rapid advances in reading the genetic code of living organisms, scientists still face a major challenge today—knowing ...

Scientists have discovered that a human receptor protein has the ability to detect individual amino acids in exactly the same way that bacteria do. The finding could lead to enhancements of drugs ...

Some cells, such as immune cells, are highly mobile—they constantly remodel their shape, migrate toward a wound that needs to ...

Imagine visiting a mangrove in the Caribbean and discovering a human as tall as Mt. Everest. Something like that happened to marine biologist Jean-Marie Volland — except instead of a human, he ...

SYNTHETIC cells made by combining components of Mycoplasma bacteria with a chemically synthesised genome can grow and divide into cells of uniform shape and size, just like most natural bacterial ...
